A novel crushing pretreatment:Inhibitory effect for micro ...
The main compositions in copper ore are quartz, feldspar, pyrite, chalcopyrite, mica, and a few other minerals. The content of quartz is highest of all of the minerals. Copper is present in chalcopyrite, and the copper grade is only %. In mineral processing engineering, copper ore is required to crush blow 74 μm to guarantee subsequent processing.
