ZINCO Zinc is one of the three most important metals after aluminum and copper among non-ferrous metals in terms of usage. These three metals are mainly used in increasing the corrosion resistance of iron and steel, in the production of special alloys and brass alloys used in the casting industry. Zinc is also used in the production of zinc plates, roofing materials and the tire industry (as ZnO). ZINC MINERALS Iron is the most used metal in industry after aluminum and copper. Significant amounts of zinc are used in increasing the corrosion resistance of iron and steel, in the production of brass and special alloys used in the casting industry, and in the production of roofing materials, tires and batteries. The visible metal zinc reserves are approximately 200 million tons in the world and 2.3 million tons in Turkey. Australia, USA, Canada and China are the countries with the largest zinc reserves. The world's zinc ore production is 8 million tons, and the scrap zinc production is around 0.5 million tons. Turkey's zinc metal consumption is around 60 thousand tons per year. 10 thousand tons of this is obtained from the metal returned from the ores sent abroad through temporary export, some of it is obtained from scrap, and the remaining 20-30 thousand tons are met by import. The most important mineral from which zinc metal is produced in nature is sphalerite. Generally, zinc minerals are classified into six groups.Sphalerite Sulfides Sulfates Carbonates Silicates OxidesUsage of Zinc as a Steel Coating Metal (Galvanization)Today, three-fifths of the zinc in the world is used in a coating method called galvanization (after the Italian chemist and inventor Luigi Galvani) to protect steel from corrosion. Left unprotected, steel will rust in almost any environment. The cost of damage caused by corrosion is estimated at $2.2 trillion per year for world economies and leads to time-consuming repairs. Steel products immersed in molten zinc baths include steel beams, roof and facade elements, poles, wires, nails, household appliances and car bodies.Barrier protection: Zinc coatings provide a continuous, impermeable metal barrier that prevents moisture from coming into contact with the steel. There is no corrosion without direct contact with moisture. However, since zinc degrades much more slowly in the presence of water and atmospheric pollutants in open-air applications, the barrier life is proportional to the coating thickness, since it corrodes slowly. The application of paint over the zinc coating, known as the duplex system, can extend the barrier coating life. Cathodic protection: Another remarkable protection mechanism is the ability of zinc to galvanically protect steel. Zinc reacts with iron to form protective oxides, carbonates, or other zinc products that are resistant to corrosion, preventing the corrosion of iron-steel by atmospheric air, water, or dust. Even if the coating is scratched, the zinc continues to form compounds and protects the iron. Zinc is a self-sacrificial metal. All metallic coatings containing zinc, including zinc-rich paints, share this beneficial property. Different technologies are used for galvanizing: In hot dip galvanizing (piece/strip galvanizing), iron sheets are dipped into a molten zinc bath. Pre-fabricated steel materials such as power distribution poles, highway guardrails and irrigation pipes can be completely coated by the hot dip galvanizing process by pre-cleaning and then dipping into a zinc bath.
