Latest Mineral Grinding Ball Mill With Low Capital Cost

Tracking comminution energy and optimising grind size for

Recovery will increase as grind size decreases, and operating costs (power, grinding media) will also increase. Incremental revenue (through head grade, metal price) needs to be compared with incremental operating costs (through power and media unit costs and specific consumption rates). For low metal prices and/or low head grades, the optimum will shift towards coarser grinds and lower

Tails from the flash flotation cells are recycled back to the ball mills for further grinding. The target final product grind size from the milling circuit is 80% passing 150 µm, although increased throughput rates in 2022 and 2022 resulted in grind size P80 coarsening to 170 to 190 µm at times. Improved process control and increased ball mill operating power draws have reduced the grind

Energy consumption is a major capital and operating cost of mineral beneficiation, and approximately two-thirds of energy processing costs can be attributed to size reduction. Therefore, comminution is often a significant factor in determining economic viability. A savings of a few percent in comminution efficiency may represent a large dollar savings for the overall mining operation. High

Fewer mills are, however, easier to control and capital and installation costs are lower, so the number of mills must be decided at the design stage. The high unit capacity SAG mill/ball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs, which has in turn made many low-grade, high-tonnage operations such as copper and gold ores
