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.);
Copper ores can be divided into various types such as copper sulfide ores, copper oxide ores, and mortar copper ores. The beneficiation methods used in these types of ores are also different, such as copper sulfide ores. The beneficiation of these ores requires grinding and flotation. and leaching steps. The raw ore is ground and then goes through a flotation process …
