Energy and Cost Comparisons of HPGR-based Circuits | E & MJ

The results showed that the HPGR-ball mill circuit achieved a 21% reduction in energy consumption over the existing SAG-ball mill circuit at the same P80 grind size of 160 mircons (μm). At a grind of 80% passing 75 μm, the HPGR-stirred mill circuit showed a 34% reduction in energy compared to the base case.

Crushing Ore Copper Ore

For the copper sulfide ore, copper recovery was independent of the crushing method since about 80–90% of copper is recovered during the initial period of leaching Recovery values were higher than those for the copper oxide ore samples, apparently due to the higher head grade, greater grain exposure and perhaps a more aggressive leach solution

Copper Mining and Extraction Sulfide Ores

The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. For example: FeO(s) + SiO 2 (s)→ FeO.SiO 2 (slag) This is very similar to the removal of impurities in the blast furnace.
