Question

what happen roasting of zinc sulphide​

Answer 1

Explanation:

During roasting, the sulfide is converted to an oxide, and sulfur is released as sulfur dioxide, a gas. For the ores Cu2S (chalcocite) and ZnS (sphalerite), balanced equations for the roasting are: 2 Cu2S + 3 O2 → 2 Cu2O + 2 SO. 2 ZnS + 3 O2 → 2 ZnO + 2 SO.
