Question

given below are the steps for the extraction of copper from its Ore write the chemical equation of the reaction involved in each case first Roasting of copper (1) sulphide second reduction of copper(1)oxide from copper (1)sulphide third electrolytic refining​

Answer 1

Cu2S+3O2___Cu2O+2SO2

2Cu2O+Cu2S___6Cu+SO2

using salt solution of copper such as CuSO4 and using impure copper as anode and pure copper as cathode

when current is on,copper ions move into the solution and same amount of Cu will transfer to cathode

the impurities of anode will settle down below the anode and pure copper is obtained from cathode
