Question

write the chemical equation for the reaction of sulphide ores​

Answer 1

The reaction of sulphide ores is i dont know

Answer 2

When sulfide ore is heated in the presence of air, it converts sulfide ore into copper oxide, and it leaves SO2. Again when the copper oxide is heated, it gets reduced to copper. Finally, pure copper will be obtained by the electrolysis process. 

Heat 

2CuS + 3O2 2Cu2O + 2SO2 

 Heat 

2CU2O + 3O2 6CU + SO2 

At Cathode: 

Cu2+ (aq) + 2e- Cu 

At Anode: 

Cu Cu2+ (aq) + 2e-
