Enhanced methods for nickel recovery from lowgrade ores
Sep 06, 2017 · Concentrating the nickel ores usually takes place close to the mine site, and involves chemical and physical processes to crush the ore and separate the nickelbearing and gangue minerals. Mining nickel directly is the obvious route to obtaining pure nickel, however, nickel can also be recovered as a byproduct of other metals.
