Grinding is continuous and fully integrated with subsequent flotation operations. SAG or AG mills. The crushed products are ground in SAG or AG mills. The self-grinding machine can grind ore without grinding media such as iron ball, or steel rod, as long as the hardness of the ore is sufficient for the rolling ore to grind by itself.

homogenization of the ore as well. The grinding plant is composed primarily of grinding mills 10 and classifiers 11. The grinding process in the flowsheet is followed by a series of separation of specific minerals. In the present flowsheet, flotation plays the main role in separation (or concentration). In
