Nickel Ore Beneficiation Plant
1. Copper-nickel sulfide ore beneficiation. When the nickel content is more than 3%, it is a rich ore, which can be directly smelted;; When the nickel ore content is less than 3%, it is mainly accompanied by a large amount of metal mineral (pyrrhotite, pentlandite, chalcopyrite)and gangue minerals (olivine, pyroxene, plagioclase, talc, mica, quartz, etc.);
