Zink Ingots

Zinc, in the form of an alloy with brass, has been known since the time of Ancient Greece, India, China, however, zinc is found in nature only in combination with other components. Prior to the invention in 1746 of a method for purifying a mixture and separating pure zinc from it, this metal was available only in alloys.

Zinc mining is carried out from polymetallic ores containing from 1% to 4% zinc sulfide. In order to obtain a sufficient amount of zinc concentrate (50-60%) for its smelting into zinc in ingots, the initial polymetallic ore is subjected to enrichment. Moreover, as a result of enrichment in parallel with zinc, the resulting concentrate also contains lead, copper, and sometimes pyrite concentrates. Further, zinc concentrates are calcined in furnaces in a fluidized bed, converting the initial zinc sulfide to ZnO oxide, and the sulfur dioxide gas SO2 formed in this process is used to produce sulfuric acid.

There are 2 ways to get pure zinc – pyrometallurgical and hydrometallurgical. The main method for producing zinc is hydrometallurgical. The pyrometallurgical method is more expensive due to its complexity, however, from the zinc obtained in this way, using additional expensive purification, it becomes possible to extract cadmium.

Zinc is used in a wide range of products and processes. It is used as a reducing agent for precious metals mined by underground leaching as well as for the extraction of silver, gold, and other metals from crude lead. Because of zinc’s great anticorrosive properties and inexpensive price, it is widely used as a protective coating for many metals and products (for example, a galvanized bucket or an automotive body like those at evchargingbaymarkings.co.uk).

Zinc is also used in zinc-air batteries, the energy consumption of which is 5-6 times higher than a conventional lead battery. In general, zinc is used in galvanizing, in medicine, in the production of alloys, rubber tires, oil paints, and also in the production of certain types of weapons.

Our company sells zinc in ingots of grades CV, Ts0, Ts1 and the corresponding GOST 3640-94. Zinc in ingots is packed in pallets. The mass of the pallet is about 1000 kg, and the whole one ingots 22-24 kg.
