Pharmacology

Zinc is an element with atomic symbol Zn, atomic number 30, and atomic weight 65.39.

How it is made

Zinc ore is mined using both underground mining and open pit mining. The mined zinc ores are too low in zinc content for direct reduction to refined metal, thus, they are first concentrated. Production of concentrates requires crushing and grinding followed by gravity or magnetic methods of separation or flotation. These processes may be combined, depending on the complexity of the ore. A caustic-leach process is used to decrease the extent of metal loss during the concentration process.

In this process, the metal is leached by caustic soda, the resulting electrolyte is purified with zinc dust and lime, and the zinc is electrodeposited. The crude zinc may be dissolved in sulfuric acid and purified by electrodeposition.

Concentration of zinc ore, roasting the concentrate, followed by thermal smelting (reduction with carbon), or followed by leaching of the roasted concentrate to extract soluble zinc, purification, and electrolytic refining.

The hydrometallurgical or electrolytical process where the zinc oxide is leached from the roasted or calcined material with sulfuric acid to form zinc sulfate solution which is electrolyzed in cells to deposit zinc on cathodes.
