Mining nickel directly is the obvious route to obtaining pure nickel, however, nickel can also be recovered as a by-product 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 a pure metal cathode. A bleed is required when certain …
Laterites make up over 70 % of both nickel production and known terrestrial resources today and have been the fastest growing source of nickel for some time.
