grinding of copper ore


Posted on December 13, 2018



3. Processing of Copper OreThe process varies slightly depending on the type of ore that is being mined. 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 of copper ore,Copper ore grinding in a mobile vertical roller mill pilot plant .Mar 10, 2015 .
