This study addresses a widespread problem confronting the mining industry: the deleterious effect of clay minerals in flotation. This problem is seemingly exacerbated by the presence of iron contamination from grinding media. The interaction of clay minerals and grinding media in copper and gold flotation was investigated in this study. A low-clay ore and a high-clay ore were …

During grinding, the extent of oxidation of chalcopyrite, a primary copper sulfide mineral, and chalcocite, a secondary copper sulfide mineral is different. Chalcopyrite is slightly oxidized, while chalcocite is strongly oxidized, resulting in different interactions with bentonite, a clay mineral. Download : Download full-size image

A microscopic examination of the Magma Copper rod mill feed revealed that quartz, feldspar, clay minerals, chlorite, iron oxides, pyrite, and chalcopyrite were present. Various metals, including iron, can act as reductants for chalcopyrite, and pyrite and magnetite are capable of increasing corrosion rates of grinding media.
