extracting copper using electrolysis?

Question

Can anyone help me with a balanced equation of extracting copper if i started of with copper carbonate, copper hydroxide and quartz. plus i have added sulpuric acid

Answer 1

CuCO3 + H2SO4 --> CuSO4 + CO2 + H2O

Cu(OH)2 + H2SO4 --> CuSO4 + 2H2O

For the electrolysis:

CuSO4 = Cu+2 (aq) + (SO4)-2 (aq)

Cu+2 (aq) + 2 e-1 --> Cu (metal)
