Copper Ore Leaching Process

The process used to treat sulfide copper ores begins at the mine site where the copperbearing minerals are physically separated from the rest of the rock the flow diagram below shows how the percentage of copper increases as the ore is refined first physi,Copper Ore Leaching Process.
