Copper Sulfide Flotation 911 Metallurgist

13/04/2016· Copper Ore Grinding Porphyry copper ores usually are medium to medium hard and require grinding to about 65 mesh to economically liberate the copper minerals from the siliceous gangue. Sometimes a regrinding circuit is advantageous on the rougher concentrate and on the scavenger concentrate.
