Figure 2 ball mill at boliden aitik copper mine. an example of an industry-standard comminution circuit providing high throughputs can be seen in fig. 3. this circuit, however, has a high, specific energy consumption per ton of ore processed, driven primarily by the low efficiency of the ball mills and the need to use steel media for grinding.
The segregated and cooled ore is fed to a one stage closed grinding circuit which consists of a ball mill and classifier. the ore is ground to a minus 65 mesh product, so that segregated copper particles are liberated from the coke and so that the sulphides present in the ore
The rod mill and two ball mills are approximately the same size for simplified maintenance. porphyry copper ores, usually medium to medium hard, require grinding to about 65-mesh to economically liberate the copper minerals from the gangue.
Due to the coarse nature of the native copper and the feed size to the gravity circuit required in the ball mill circuit up to 10 mm, there were only two gravity options reviewed for this circuit. the first was dense media separation but this was deemed to have too high a capex and opex and was rejected on its inability to process ore finer ...
