1. Introduction. The presence of clay minerals with valuable minerals is unavoidable in many ore bodies. In this case, the associated clay minerals are considered as gangue and are known to reduce the efficiency of various processes involved in mining operations, for example, crushing, grinding, flotation, dewatering, filtration etc. Profitable mining of clay-containing low-grade ores is the ...
