Zinc processing, the extraction of zinc from its ores and the preparation of zinc metal or chemical compounds for use in various products. Zinc (Zn) is a metallic element of hexagonal close-packed (hcp) crystal structure and a density of 7.13 grams per cubic centimetre.
Zinc oxide (ZnO) is the most widely used zinc compound and can be produced according to a number of different processes. In the French (indirect) method, zinc oxide is produced by the combustion of zinc metal. When zinc oxide is extracted from zinc ore or smelter by products (e.g., using oxidized zinc) it is called the American or the direct ...
Zinc is usually a gray metallic color, but it can be polished to a shiny silver luster. In nature, it is only found as a chemical compound, not as pure zinc, and can be used as a raw material for castings and coatings. During the era of the Roman Empire, people used zinc to alloy copper into brass for weapons.

Sep 10, 2006· The raw material used for the production of zinc is zinc concentrate, which is the result of a flotation process after the ore has been mined and milled. The zinc ore contains 1-15% zinc whereas the concentrate typically contains approx. 55% zinc, 6.5% iron and 32% sulphur together with other elements at much lower levels.
Because its position in the reactivity series of metals, zinc can be 'just' extracted using carbon (coke) in a high temperature smelting furnace. – it is a sort of displacement reaction. Zinc is extracted from either zinc blende/sphalerite ore (zinc sulphide) or sometimes calamine/Smithsonite ore (zinc carbonate).
zinc oxide + carbon monoxide ————> zinc + carbon dioxide. Describe the essential reactions in the extraction of iron in the blast furnace. An ore is a rock from which metals can be extracted. The main ore of iron is hematite, which contains large amounts of iron(III)oxide.
Therefore much lead ore is obtained as a byproduct of other metal mining, usually zinc or silver. Only half of all lead used yearly derives from mining, as half is recovered through recycling, mostly of automobile batteries. Besides the ore itself, only a few raw materials are necessary for the refining of lead.
Zinc ores and extraction 2. Zinc ores and extraction 2. How we extract zinc from its ores. Stage 1 The low concentrations of the zinc sulphide mineral in most zinc ores mean that the ore must first be concentrated before extracting the metal The zinc blende (sphalerite zinc sulphide)is first crushed to powder and then treated by froth . Get Price
The first process in the extraction of zinc is the concentration. As shown in the diagram below, this process involves the implementation of froth floatation method for the extraction of zinc ores from zinc blende. Zinc blende is mixed up in a large tank consisting of a mixture of pine oil and water.
