Selfcleaning screen media is also available on this modular system,»improving the efficiency of a sag mill treating gold ores; performance and manipulate feed size to obtain efficiency improvements reliance of ag/sag mills .
· However, the SAG route is more powerintensive and, for very hard ores, comes with some process risk in predicting performance. More recently, a hybrid solution has become available in the form of high pressure grinding rolls (HPGRs), which can replace the third stage of crushing and also the SAG mill.
· Apr 24, 2014· Following implementation of these strategies, the SAG mill throughput when treating the harder copper/zinc ores increased from 2,750 tph to an average of 3,600 tph, and the optimization of the overall process improved energy efficiency, resulting in . Factors Affecting Ball Mill Grinding Efficiency
· Sulphide coppergold ores are usually sorted by flotation. The standard comminution process to grind the ore to flotation fineness, mostly consists of coarse crushing followed by SAG milling or wet ball mill circuits, or alternatively multiple stage crushing followed by rod and ball milling.
Figure 1 Gold ore characterization flowsheet (Brooy, 1994) The selection of a flowsheet for free milling ores is relatively simple compared to others. The major factors include comminution circuit selection, heap leaching use, treatment of ores with high silver content, and flotation options for sulfides.
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 lowgrade, hightonnage operations such as copper and gold ores feasible. Future circuits may see increasing use of high pressure grinding rolls (Rosas et al., 2012).
