Stainless steel media minimises the amount of iron oxidation products originated from grinding media and therefore the lignosulfonate base polymer F-100 may mitigate the negative effect of clay minerals resulting in the improved copper and gold flotation.Grinding Media Balls for Mines and Minerals Processing,Copper. Bauxite. Lead – Zinc. Rock phosphate. Metal slag. Coal. There is no standard solution for mineral industry and wear rate of grinding media varies from mine to mine, ore to ore and even for the same ore time to time. Different alloys are recommendedCopper mining - Secured recovery | Magotteaux,The statistical analysis showed clearly that the copper recovery had decreased by at least 1.3 % with the change in grinding media alloy. This represented a gross loss in revenue of 9 million USD/year. The site immediately requested that Magotteaux supply grinding media with the initial alloy.
