Mining Industry: What are some good ways to extract copper from .

Sulfide ores are first put through a jaw or gyratory crusher to reduce the rocks to about 7 – 8 inches. This material is then fed to a secondary grinder that further reduces the size to about 1 – 2 inches. The next step is to feed the crushed ore into a wet grinding process in tumbling mills. These mills contain the ore, water and.
