wastes in mining nickle

Mining nickel directly is the obvious route to obtaining pure nickel, however, nickel can also be recovered as a byproduct of other metals. For example, copper electrolysis requires a bleed to eliminate the buildup of impurities that accumulate over time as a result of the electrorefining of impure copper anode to produce pure metal cathode.
