Zinc oxide is prepared commercially by two methods: the American (or direct) process, which uses zinc ore and concentrate, and the French (or indirect) process, which uses zinc metal. Some 54% of US zinc oxide production is from zinc ore and concentrate (American process), 33% from slab zinc (French process) and 13% from secondary material.

The main zinc ores are blende (ZnS), smithsonite (ZnCO3), and calamine (Zn4Si2O7 (OH) 2, H2O). Zinc ores are usually proceeded by froth flotation, followed by leaching, and electrometallurgical extraction. After the ore is extracted, it undergoes physical treatments consisting of eliminating as much as possible of the gangue. In the Read more

Zinc is extracted from the purified zinc sulfate solution by electrowinning, which is a specialized form of electrolysis. The process works by passing an electric current through the solution in a series of cells. This causes the zinc to deposit on the cathodes ( aluminium sheets) and oxygen to form at the anodes.

Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless
