Chalcopyrite ore beneficiation process and method
The present invention relates to a mineral processing technology and method for refractory chalcopyrite ores, particularly to a mineral processing technology and method for the separation of chalcopyrite from multiple natural types of copper ores containing chalcopyrite, pyrrhotite, talc and serpentine, which belongs to the technical field of mineral processing. It's characterized by: conducting a two-stage grinding on the chalcopyrite ore, with each grinding stage followed by size grading, and treating ores in different size fractions separately, wherein coarse-grain ores are separated in the presence of xanthate, with calcium oxide and CMC controlling the pH and acting as depressor respectively, while fine-grained ores are subjected to rougher in the presence of kerosene, and subsequently subjected to cleaner in the presence of xanthate.
