Question

Write chemical equation for obtaining zinc metal from zinc sulphide

Answer 1

zinc sulphide

Explanation:

The crude zinc sulphide ore is heated strongly in excess of air. Zinc sulphide is converted into zinc oxide. This process is known as roasting .

2ZnS(s)Zinc sulphide+3O2(g)→2ZnO(s) zinc oxide+2SO2(g) Sulphur dioxide  

The crude zinc carbonate ore is heated strongly in limited supply of air. Zinc carbonte is converted into zinc oxide. This process is known as calcination .

ZnCO3(s) Zinc carbonate→ZnOsZinc oxide+( Sulphur dioxide)(CO2(g))

The zinc oxide is reduced to zinc by using a reducing agent such s carbon

ZnO(s) Zinc oxide +CCarbon(s)→Zn(s)+CO(g)Carbon monoxide
