Perform an exergy analysis for comminution work in a laboratory sized dry ball mill. This study analyzes the exergy efficiency of comminution using a laboratory sized dry ball mill and a copper mineral ore from central Chile. In this research, we develop a minimum work index from uniaxial compression tests results on the ore fitted to Morrell ...

For the mining industry, our semiautogenous (SAG) grinding mill uses a minimal ball charge in the range of 615 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.

For design purposes, you need an estimation or prediction of your SAG Mill's tonnage; well, there are 3 ways to generate good rock "ore" hardness testing data for SAG and ball mill circuit grindability from half drill core. We can abbreviate the discussion by saying there are three "faiths" of grinding, and there are smallscale tests suitable for all three of the major faiths of ore ...

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).
