Name the process used for the formation of blister Cu by following reaction :(unbalanced reactions)
2Cu2S+3O2→Cu2O+SO2
Cu2O+Cu2S→Cu+SO2The process is called bessemerisation. Cu produced by Bessemerisation is known as blister Cu which is 95% pure. The balanced chemical reactions are as shown.
2Cu2S+3O2→2Cu2O+2SO2
2Cu2O+Cu2S→6Cu+SO2
