The mechanism which underpins the interaction of oxidized chalcopyrite and chalcocite with bentonite representing the clay mineral was explored. Outcomes of this study will guide the industry to implement grinding strategies to improve the extraction of copper minerals in the presence of clay minerals. 2. Material and methods
اقرأ أكثرFor the mining industry, our semi-autogenous (SAG) grinding mill uses a minimal ball charge in the range of 6-15 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.
