Keep up-to-date with the current mineral of the month! From aluminium to zinc we’ll cover an array of metals and minerals that are essential to daily life. Click here to find out the mineral for this month.
Aggregate is a general term that basically refers to small pieces of rock, including sand, gravel and crushed rock. It may be the most taken for granted raw material. Much like electricity or water, it permeates our lives, but our conscious awareness of it is minimal. However, if you take a look around any part of our built world, you will see that it surrounds you. It’s easy to recognize because it looks precisely the same in nature. Sand and gravel are simply sieved and classified, and crushed rock looks just like angular pebbles.
Aggregate in daily life
Each application for aggregate requires its own grain size, and it is used for a wide variety of construction purposes, either in bound form or as loose material. Bound forms include asphalt and cement concrete, while loose aggregate is used for constructional filling, in railway or roof ballast, in drainage filters and so on. Imagine if we couldn’t build roads or design new buildings for lack of sand.
It may be frequently overlooked, but aggregate is the most used mineral resource in the world. Dutch use is about one full bucket per person each day! Next time you drive down a road or walk into work or even relax at home on the weekend, remember that aggregate makes it possible.
Baryte is a white (or grey if there are impurities) mineral that is commonly found in lead-zinc veins that occur in limestones, around hot spring and with hematite ore. The name baryte comes from the Ancient Greek term for “heavy”, as it is a very dense. It also has a high fusion point and is inert, non-toxic and almost insoluble in water. Baryte is the main source of the element barium, which does not naturally occur in a pure form.
Baryte in daily life
The majority of Baryte is used as a weighting agent for drilling fluids in oil and gas exploration, preventing blowouts. However,its properties make it a perfect mineral for many other applications such as filler for paint, rubber, ceramics or glass, corrosion-resistant coating for automobile finishes, sound reduction in engines and for radiation shielding in high-density concrete. Barium carbonate is used in the manufacturing of LED glass for computer and television screens.
Barium is an essential part of a barium meal, which is used for certain medical tests.The patient swallows a barium solution before X-ray imaging is taken, and because barium is not water-soluble, the solution coats the digestive tract without being absorbed, allowing doctors to examine these areas of the body more closely.
Along the mostly white Mediterranean landscapes from Spain to Greece, there are colourful patches of rock with a red-pink-purple-ochre-brown spectrum. This rock is called Bauxite, named after a small town in southern France called Les Beaux-de-Provence. It means beautiful or handsome in French.
Bauxite in daily life
90 percent of Bauxite is used for making alumina, which is largely used to produce aluminium. The other 10 percent is put toward a variety of uses such as abrasives, water purification, and refining kerosene. But of course, aluminium permeates our lives, from the aluminium foil we use to preserve leftovers to the canned beverages we might enjoy with those leftovers to the airplanes we travel in to visit family. Aluminium, though artificially made, is possible because of those colourful Mediterranean rocks
Beryllium is a silver-white relatively hard but brittle metal. It is light (1.5 times lighter than aluminium) however it is strong (stronger than steel) and heat resistant (can withstand heat up to 700-800 Degrees Celsius). Beryllium is rare mineral, with an average concentration in the earth’s crust of about 4ppm (parts per million e.g. there are 6mg of the minerals per kg of rock). In contrast to other rare metals, it is mostly concentrated in the form of its own minerals among which beryl, phenacite and bertrandite are of commercial importance. The main beryllium raw material is bertrandite ore.
French chemist Louis Nicolas Vauquelin, who had discovered beryllium, suggested calling it “glucinum” (from Greek glycos- sweet) due to the sweet taste of its salts.
Uses of Beryllium in our daily life
Beryllium weakly absorbs X-rays, thus it is used for manufacturing X-ray tube windows where the X-rays come out and wide-range gamma ray detectors, through which radiation enters the detector. It is also readily found in objects such as the jewellery we wear, needles for injections, springs for Swiss watches (an alloy of nickel, beryllium and tungsten) and ball point pens.
Beryllium is also a material for manufacturing heat shields and gyroscopic devices for guidance and orientation systems in high-speed aircrafts, space vihicles, submarines and surface vessels.A special grade of metal with extremly high reflectivity was developed for space and optical mirrors.
When it occurs in its elemental form in nature, bismuth is a white, brittle metal, but oxidation can give it a pink tint. However, most of the time bismuth is found in minerals such as bismuthinite and bismite. There are natural bismuth deposits, the largest of which are in Bolivia, but the metal is more often produced as a by-product of mining and processing lead and tungsten.
Bismuth has several characteristics that make it unique. It is repelled by a magnetic field, expands when frozen, has a low melting point and has one of the lowest levels of thermal conductivity. For a heavy metal, its toxicity is unusually low. Now that we are aware of the dangers of lead, bismuth alloys are often used as a replacement.
Bismuth in daily life
Bismuth is non-toxic and considered to be an eco-friendly material. This makes it ideal for uses in pharmaceuticals and medicine, the animal-feed industry and cosmetics. It is most recognizable in the form of Pepto-Bismol and De-Nol, but it has also been used in anticancer, antitumor and antimicrobial studies.
Bismuth is also extremely useful in a number of industrial applications such as coatings, pigments, and electronics. When added to other metals such as lead, iron, tin or cadmium, it forms low-melting alloys that are used in fire sprinkler and detection systems, electrical fuses and solders.
Chromite is not especially exciting to look at, but it is important to our daily lives as the number one mineral source of chromium. Chromite is a dark grey to black mineral made up of chromium, iron and oxygen. The chromium that is extracted from chromite minerals is used to make chrome plating and to create industrial alloys. Its hardness and resistance to corrosion make it one of the most important industrial metals used today, and it cannot be replaced with other materials.
Chromite in daily life
You don’t have to look far to spot chromium. In addition to its industrial uses, this metal is used to make stainless steel. This combination of steel and chromium makes metals that are durable and can withstand high temperatures. You can find it in your pots and pans, most flatware and many kitchen appliances. These same properties make stainless steel excellent for use in food processing equipment and medical and dental tools. Chromium is also used in glass, glazes and paint as a pigment and in processing leather.
Copper is a mineral with many benefits! Not only is it the best conductor of electricity and heat, it also has ductile and malleable properties making it easy to form into various shapes including wires and jewellery.
Additionally, copper has a germicidal effect which neutralises many germs. It is often used as an alloy with tin (Sn) in things like doorknobs due to its automatic disinfecting qualities. This property was initially observed in Classical antiquity and copper was used by ancient civilizations as medicine for treating wounds.
Uses of copper in our daily life
Due to its excellent electrical and thermal conductivity, copper is found in many household items like piping, lightning rods, and cooling units such as refrigerators, air conditioners and other electrical appliances. It is also widely used in coins, transport (e.g. trains) musical instruments, phones, computers, wind turbines, photovoltaic cells and electric generators.
The dolomite mineral is a beautiful one due to it’s crystallising properties and white, tan, gray or pink colouring. It has an alternate structural arrangement of calcium and magnesium ions and has similar uses to limestone.
One of the first people to describe this mineral was in 1791 by the French naturalist and geologist Deodat Gratet de Dolomieu. He noticed it in the first buildings of the old city of Rome and later from samples collected in the Dolomite Alps of Northern Italy.
Uses of Dolomite in our daily life
Dolomite can be ‘hidden’ in many products we use everyday. For example, it is commonly used as antacids (neutralizes stomach acid), a base for face creams, baby powders, or toothpaste, calcium/magnesium nutritional supplements for animals and humans. Finely ground dolomite is used for filler applications in plastics, paints, rubber, adhesives and sealants. Pure white (high brightness) filler grades are preferred in this case.
The most important use, by volume, is in the construction industry. Dolomite and limestone are used in similar ways; they are crushed and used as an aggregate for both cement and bitumen mixes. Road builders mix it with concrete and asphalt and it is used as a ballast for railroads. Like limestone, dolostones are used as a construction resource for local consumption because of low transportation cost. Because its yellowish colour, dolostones are used as building stones and gravel for garden paths and driveways (e.g. “golden” gravel).
The name feldspar is given to a group of minerals that contain alumina and silica in their chemistry (including aluminium silicates of soda, potassium or lime). About 60% of the earth’s crust is made from feldspar making it the most abundant group of minerals.
More than 70% of the feldspars produced in the EU are used in the ceramic industry and most of the rest is in glass production. In ceramics, manufacturing feldspar is the second most important ingredient after clay. Feldspar does not have a strict melting point since it melts gradually over a range of temperatures which greatly facilitates the melting of quartz and clays. Feldspar improves the strength, toughness and durability of the ceramic body and cements the crystalline phase of other ingredients, softening, melting and wetting other batch constituents.
In the manufacture of glass, the alkali content in feldspar acts as flux, lowering the glass batch melting temperature and thus reducing production costs.
Gold had a great and frequently mystic influence on people from the beginning of mankind, being used for jewellery, treasure, raw material, as a measure for money (universal currency) and has also been associated with divinity and royalty, promoting the yellow colour as a noble one in many civilizations. Additionally, it is also a symbol of the winners (gold medalists) and persistence (most wedding rings are made of gold). More recent medical and high-tech uses complete the importance of the metal in everyday life.
Pure gold is too soft for most manufacturing purposes. This is why it is used in alloys with other metals, which can alter its colour, generating varieties of white gold (allied with nickel, silver or palladium), red or pink gold (with copper) or blue gold (allied with iron). On the purpose of briefly stating of gold content in an alloy, the karat/carat system is used. Pure gold has 24 karat while an alloy with 50% Au has 12 karat, one with 75% Au has 18 karat etc.
Uses of gold in our daily life
Maybe the oldest use of gold is in jewellery and ornamental objects. This is the use of more than 50% of the gold mined to present. Beside its use in adornments for people’s personal use, gold is employed for the ornamentation of buildings (exterior and/or interior) as well as coating of palaces, temples, churches, statues, icons, books, frames etc.
Like copper, gold is a very good electricity conductor and it is used for fuses, switches, connectors, electronic circuits and chips in computers, cell phones or TV sets. Gold is also used in catalytic convertors or as lubricant against cold welding (very useful in space, where many other lubricants can break down or evaporate).
Graphite has long-standing uses in lead pencils and as a mechanical lubricant, but today graphite is also a high-technology material used in composites, electronics and foils. Graphite has a unique set of properties that makes it an essential component in an extremely wide range of applications.
Graphite is electrically and thermally conductive, it is both lubricating and refractory and retains strength at very high temperatures. Graphite is chemically resistant and the mono-layer version - the graphene building blocks - is one of the strongest materials ever tested. The main modern uses of natural graphite is in high-temperature applications, such as crucibles and furnaces, in steel production, brake pads and linings for cars, and in electrical applications and batteries for the complete range of portable consumer electronics. It is also important in electric vehicles. In fact the so-called lithium-ion battery, found in almost all mobile electronic equipment, contains twice as much graphite as lithium. Fuel cell technology is expected to increase demand for natural graphite significantly.
Graphene is predicted to be THE material of the future - a one atom thick layer of graphite carrying all the properties of ordinary graphite in combination with extraordinary strength, stability and flexibility, low weight and transparency. According to the European Commision report on defining critical raw materials, the EU is 95 % dependant on imports of graphite to supply the European industry. The criticality issue probably mainly applies to the flake segment.
Gypsum is one of the oldest minerals known to be used by man. Its dehydrated form is what we commonly call plaster. It was used in ancient civilizations in Egypt, Rome, Mesopotamia, as well as Medieval England for reproductions of statues and casts of human faces. The inhabitants of Pompeii were cast in gypsum.
It was also frequently used in ancient times for “plastering of wine,” namely in France and Sicily. This was a process in which Plaster of Paris was added to wine to improve its acidity.
Uses of gypsum in our daily life
Today we still take advantage of gypsum as a soft mineral. It is used in the ceramics industry for molds and master models, in orthopaedics for plaster casts and in orthodontics for dental impressions. However, we have also discovered additional uses beyond making impressions. In buildings, it is used for walls, ceilings, covered plasterboard, plaster blocks and stucco, and it is a key ingredient in cement, where it delays the setting time.
Additionally, gypsum is used as a filler for pills, was previously used to produce chalk (now replaced by calcium carbonate rocks), and as a soil conditioner and component in fertilizers.
Almost all (98%) of globally produced iron ore goes to making steel. Steel is an alloy of (mostly) iron, carbon and other elements with carbon content less than 2%. Steel is the most used and important engineering material in the world due to its high strength relative to weight and cost effectiveness. The usage of iron (in steel) is about 20 times more than all other metals usage put together. About 60% of iron and steel products are used in construction and transportation. 20% are used in machinery manufacture.
The rest are used for packaging, in power and energy sectors and in various household appliances and other equipment.
Uses of iron in our daily life
Iron has been used throughout history for many purposes. Wrought iron can be used for seating, fences, and other decorative purposes whilst cast iron is commonly used in kitchen utensils such as frying pans.
Iron is often combined with steel to create an alloyed steel which and is ideal for use in construction. For example, alloyed steel is frequently used for the framework of a number of storage buildings, as well as in the construction of some parts of automobiles and the hulls of large carrier and passenger ships.
Kaolin is a clay mineral which has a low shrink-swell capacity. It is a soft, earthy white mineral and has a wide variety of applications, most of which we use every day. The principal uses include ceramics (as the principal filling mass as well as the enamel cover, both to be fired), refractory and high-refractory (mullite) ceramics, paper industry (both filling and coating material, namely in chalk papers), rubber industry (filler), industry of plastics (filler) and even cosmetics and medicaments (filler in pills and tablets). A progressive kind of use of kaolin includes glass fibres.
In many parts of the world, it is colored pink-orange-red by iron oxide, giving it a distinct rust hue. Lighter concentrations yield white, yellow or light orange colors.
Uses of Kaolin in our daily life
Kaolin is in nearly everything! From toilet paper, soap and toothpaste to medicines in the form of tablets and pills, where more than 99 % of the mass is pure kaolinite. All kinds of whitewares, made from porcelain or stoneware (or even plastics) contain kaolin e.g. plates and saucers, dessert plates, dishes and salad bowls, little pots. Kaolin is also in table napkins and in most stationary products.
Lead was one of the earliest metals known to humans. The Chinese used it to forge coins as long as 4,000 years ago, and the ancient Romans, upon discovering its corrosion-resistant properties, used lead for water pipes and bath linings. Of course we now know of the dangers of using lead for some of these items, but when managed properly lead is still an extremely useful metal today.
Lead is soft and malleable, highly resistant to corrosion and is a poor conductor of electricity. When you first cut it, lead reveals a silvery-blue luster, although it immediately darkens to a dull gray when it hits the air. Lead is abundant in the form of ores that also contain minerals like zinc, copper or silver. The most commonly known lead-containing ore is galena.
Lead in daily life
Now that we know lead requires special care, we’re able to capitalize on its unique properties without risk to human health. This is great news because lead is abundant and affordable!
Lead is a significant component of car batteries, aprons that shield patients from x-ray radiation, and as a stabilizer in PVC pipes. Its low melting point makes it the most common soldering material. And the resistance to corrosion combined with lead’s high density that gives it a high weight-to-volume ratio makes it ideal for use in the ballast keel of sailboats. Additionally, lead has many miscellaneous uses, such as in organ pipes, photovoltaic solar energy cells and infrared detectors.
Lepidolite is an attractive mineral that is usually found in its lilac-grey form. However, it can also be pink, rose-red, yellowish, white or colourless. Lepidolite is a member of the mica group of minerals, and it is the most abundant mineral that contains lithium.
A major application of lithium is in rechargeable batteries. Hybrid and electric cars, mobile phones, laptops and digital cameras are all powered by lithium. These devices permeate our lives and are only becoming more prevalent. The batteries of electric cars in particular require large amounts of lithium, and the growing demand for clean-energy vehicles is making lithium supply a critical concern for European society.
Lepidolite in daily life
While lepidolite is rarely used directly, the lithium it contains has a wide range of applications in addition to its use in rechargeable batteries. Some non-rechargeable batteries like those in pacemakers, toys and clocks also need lithium. And it is also a main ingredient in medications for treating depression, bipolar disorder and schizophrenia.
Lithium metal is often combined with aluminium and magnesium to produce lightweight, strong alloys for use in armour plating, aircraft, bicycle frames and high-speed trains. In its various forms, lithium is used in special glasses and ceramics, air conditioning and industrial drying systems and all-purpose and high-temperature lubricants.
Limestone in daily life
The extent and variety to which we utilize limestone is great. Its industrial applications include the use in a number of construction materials, both directly as cut stone and with other minerals such as in cement. It’s also used in the production process for steel and for purifying waste water.
Our homes are filled with limestone from paper and glossy magazines to impact resistant plastic, even in many toothpastes. Nearly one third of glass is made up of limestone, and lime is used to absorb impurities in sugar during processing. Additionally, we have lime to thank for the foods we consume. It’s an effective product for reducing acidity and releasing nutrients for plant use in gran and vegetable fields. The cows who produce our milk need lime in their feed so they have enough calcium in their diets, and the chickens who lay our eggs need it to produce strong shells.
The mineral magnesium carbonate, more commonly called magnesite, is named for the significant amount of magnesium it contains. It is commercially processed and refined into several different forms, which makes magnesium useful in many different applications. A notable characteristic of magnesia, or magnesium oxide, is that it has an extremely high melting temperature. This makes it a useful refractory material for many processes in steelmaking, metallurgy and ceramics.
Magnesite in daily life
Magnesite is less obvious in our daily lives, but it is used in many processes that are necessary for products we interact with and consume on a regular basis. One form of magnesite, called caustic calcined magnesite, is used in fertilisers and livestock feeds, waste and water treatments and pulp and paper. Magnesia’s high melting point makes it a common material used for making bricks used to line kilns, industrial ovens and blast furnaces used to create products like ceramics. Additionally, magnesite can be used as a binder in flooring material and as a catalyst and filler in synthetic rubber production.
Unlike the coal used for producing electricity, coking coal is used exclusively for steel-making. The coal is subjected to temperatures around 1000-1100°C in the absence of oxygen to remove impurities. This process results in a hard, porous material that is almost pure carbon called coke.
Metallurgic coal in daily life
This type of coal is not directly used in our daily lives, but the steel it makes possible is all around us. The global production of crude steel in 2017 was 1.6 billion tonnes. Large quantities of steel are required for the bridges, railways, airports, skyscrapers and that make up our infrastructure. Even pylons that hold up power lines are made of steel. Stainless steel can be found in kitchens all across Europe in pots and pans, appliances, serving dishes – even steel wool. It’s also present in many kinds of surgical equipment.
Coking coal even contributes to reduced dependence on thermal coal-based energy by helping to produce the steel needed for alternative energy sources such as in wind turbines.
Nickel in daily life
Most people interact with nickel every day through stainless steel. Nickel helps make this material resistant to corrosion, scratching, denting, and it does not react with foods that are highly acidic or alkaline. It’s also very safe, which makes it perfect for cookware and cutlery. Stainless steel a popular choice for kitchenware designers like the famous Danish designer Georg Jensen Leaf, whose stainless steel bowls are of the highest quality.
Stainless steel is also used in construction and aircrafts, and nickel is critical for rechargeable batteries, wind turbines, surgical equipment, mobile phones and water purifiers. Products that contain nickel have long life-spans and are highly recyclable.
Uses of potash in our daily life
Potash is used in a diverse range of fertiliser products, varying from granular and coarse grades suitable for direct application as a single nutrient fertiliser through to fine grades for the production of more complex fertilisers, consisting of nutrient blends. Global potash demand is primarily linked to agricultural productivity, which is growing rapidly. About half of the fertiliser used globally is applied to cereal crops. Potash is also used in animal feed supplements, which aid animal growth and milk production. Small quantities of potash and derived compounds are used by the chemical and pharmaceutical industries for the manufacture of a diverse range of goods, varying from soaps, the production of speciality glass, explosives, matches and pyrotechnics, water softening, and meat curing.
As June begins, the Northern Hemisphere is enjoying the return of the sun. Long summer days are approaching and with them, greater opportunity for capturing solar power – something that wouldn’t be possible without Quartz.
This mineral is found in various forms, most commonly in quartz sand as well as in rocks such as granite, quartzite and quartz sandstone. In some parts of the world it is even mined in the form of subterranean crystals, but it must undergo tremendous heat and pressure to crystalize. Quartz was once a minor non-metallic raw material, but demand has consistently grown over recent decades.
Quartz is stable, chemically pure, has high transmissivity to light and a high resistance to heat. The qualities make it highly valuable in a world that’s constantly developing new technology.
Quartz in daily life
Aside from jewellery, some of the earliest uses of quartz crystals were in radio oscillators and clocks, and later computer chips. Today, the physical properties of quartz make fused quartz ideal for semiconductors used in solar panels. In this environmentally friendly technology, quartz takes the form of silica as thin films and silicon wafers that are vital to solar panels. Using quartz even makes solar panel production cheaper, which helps overcome a big obstacle that solar power faces.
And when you look around your everyday world, quartz is there. You might even be looking through it right now. Quartz sand is used to make glass that’s used all around us, in windows, fiberglass, television tubes, spectacles and the screen of your iPhone. Quartz sand is even used in water filtration, so you can thank this mineral for the clean water coming from your tap.
Salt in daily life
Without sodium in our diets, our cells wouldn’t be able to function properly and we would suffer nausea and vomiting, fatigue, headaches, weakness, spasms, seizures, or even coma. But salt is easy to consume. It enables our sense of taste and brings out other food’s natural flavours.
Salt is also used to make saline solutions for intravenous therapy drips, cleaning contact lenses or new piercings, and nasal irrigation. Plus the wintry roads we face in February are much safer with salt helping to melt the ice.
Sulfur in daily life
Sulfur’s bright yellow colour and distinct physical properties made it a recognized mineral even in ancient societies. Sulfur is highly flammable and when burned, produces a flame that can be hard to see in daylight, but darkness reveals a subtle blue light. It’s what some ancient peoples called “brimstone”. And as far back as the 7th century, the Chinese were using sulfur to make gunpowder to launch rockets and shoot projectiles.
Today, the majority of sulfur is used to produce sulfuric acid for fertilizers that help grow the fruit and vegetables we need for proper nutrition. Sulfur itself contributes to our overall health when consumed. It’s also still used in gunpowder, matches and fireworks. That smell when you light a match is caused by sulfur. Other uses of sulfur include pharmaceuticals, soaps, textiles, papers, processed rubber, leather, paint, dyes and food preservatives.
Talc is the softest known mineral and chemically inert, and this makes it perfect for a wide variety of uses. It’s a major component of ceramics, and even the Vikings used talc-rich soapstone to create cooking-pots. They took these pots with them on their travels and sold them both abroad and at home. Soapstone's softness also made it possible for Native American Indians to carve it into smoking pipes.
Today, we encounter talc constantly in our daily lives. As the weather gets warmer, we’ll see more construction projects around our towns. If you notice new roofs being installed, you’ll know talc is being used for weather resistance where you live. You may even want to do some projects in your own home, in which case you’ll likely use talc in floor and wall tiles or to put on a fresh coat of paint.
Talc in daily life
Talc is just about everywhere you look. In addition to certain construction materials, talc is in the gum you chew, the paper you write on, and a large number of cosmetics. It’s used as a carrier for medicated powders and a coating for pills. Talc is a safe carrier for food colourings and helps stop foods like rice form sticking together.
It’s even in your electronics. Talc is used as an insulator in wires, and its flame and heat resistant properties make it perfect for keeping your computer and TV safe from overheating, as well as various parts of your car and tyres.
Due its hardness and wear resistance, over 50% of the world tungsten production is used in producing hard materials based on cemented tungsten carbide, by far the most common tungsten compound. Tungsten carbide-based materials have a great variety of applications, including the use in cutting and drilling tools. The second largest application is in the production of special hard steels, with extreme resistance to corrosion and high temperatures. The high melting point making pure tungsten metal suitable for high temperature applications in energy- and lighting technology, and in the space industry.
The high density of tungsten is used in weights and counterweights for vibration damping in aerospace, automotive, sport and telecommunications applications.
Tungsten serves also as a substitute for lead and is used as radiation-shielding in medical engineering. X-ray tubes for medical use have emitter coils made of tungsten. Tungsten is also used in microchip technology and liquid crystals displays.
Uses of Tungsten in our daily life
Tungsten is used in mobile phone vibration caused by an unbalanced-mass motor made of tungsten heavy metal as well as in cars with tungsten based elements in electronics, window heating system, tire studs and vibration damping in diesel engines using crankshafts made of high-density tungsten heavy metal. It is likely that the ballpoint pen you use to write with contains tungsten carbide balls and it is also possible that your dentist uses tungsten based drilling tools.
Zinc is a naturally occurring, lustrous, bluish-white metallic element. Commonly it appears dull in many applications although in some it has a silvery appearance. It is the 24th most common element in the earth’s crust and it is essential for human growth (e.g. zinc deficiency in humans can cause birth defects, lead to delayed healing, cause skin irritation and loss of the sense of taste, to name a few). Zinc prevents rusting or corrosion of steel when applied as a protective surface coating by galvanising (electro-plating). Corroding steel loses surface flakes that detach and expose more steel to corrosion. Coating steel with zinc oxide provides a continuous surface layer that protects steel from corrosion. Zinc is also very malleable, making it an easy mineral to cast into many shapes.
Uses of zinc in our daily life
Zinc has many uses! It is perhaps most commonly known for it’s use in sun-screen lotions but it can also be used to combat colds, as an antiseptic ointment, in calamine lotion and anti-dandruff shampooed.
Its main uses are: galvanizing (50%); die-casting (17%); brass making (17%); miscellaneous (16%) such as chemicals, pharmaceuticals, plastics, paint and coinage.
