IntroductionThe reduction of talc recovery in copper-cobalt flotation concentrates is very crucial. In fact, a high talc content into the concentrate lowers the copper-cobalt grades and causes problems in the smelters due to the resulting high MgO content (Pugh 1988;Klein et al. 2016;Kime and Kaniki 2017), forcing the smelter operators to impose penalties for the concentrators.
