Similarly, the presence of nonliberated or locked cobalt minerals in quartz will affect the cobalt recovery during flotation, with cobalt being lost to tailings. For both processing options, the only solution is to increase the specific surface area of ore particles by grinding the ore to a finer size. Carbonates

Although ultrafine grinding is not considered as a chemical oxidation process, there is evidence to suggest that for certain ore types, grinding ores to lower than 10 μm size enables sufficient liberation of gold from goldbearing iron sulfides. The extent of oxidation of sulfides after ultrafine grinding is not accurately known and needs ...
