Copper can be extracted from the mineral malachite, Cu2(CO3)(OH)2, which is 57.48% Copper. The typical method of recovering / extraction the copper from the malachite ore is:

1) First, crush the ore
2) Pile the crushed ore in to a heap on a liner
3) Sprinkle the pile with sulfuric acid
the base reaction is: Cu(OH)2 + H2 SO4 = 2H2O + CuSO4
4) Drain the recovered liquid into a container
5) Add some old iron pieces
the reaction is Fe + Cu2+ = Fe2+ + Cu
7) you have recovered the copper

Are you sure you did not mean the other way around? Malachite is a copper compound and copper is an element. One extracts an element from a mineral or compound, not the compound from an element.
