how is zinc extracted from its ore

Depending on whether sulphide or carbonate ores used for the extraction, the concentrated ore is either roasted (or) calcined. The zinc oxide obtained after roasting (or) calcination is reduced to zinc in vertical retorts where zinc oxide is powdered, mixed with coke and clay and then made into small briquettes.

Extraction of Zinc from Zinc Blende | thechemshoplmxl

The chief Ore of zinc is zinc blende. The extraction of zinc from zinc blende involves the following steps. Concentration: The ore is crushed and then concentrated by froth-floatation Process. Roasting: The concentrated ore is then roasted in the presence of excess of air at about 1 2 0 0 k: 2 Z n S + 3 O 2 → Δ 2 Z n O + 2 S O 2

Secondly, there are two ways to obtain zinc from zinc blende, usually done through reducing its ore to zinc with carbon and limestone in a smelting furnace, or electrolysis. However, Zinc cannot be extracted in its ore but we need to roast it in air first to produce impure zinc oxide and sulfur dioxide gas by heating it at about 900 °C.
