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.copper production grinding crushing,The Concentrating Process - Britannia Mine Museumchemical bonds and separating the elemental copper from the other mineral components is . in the milling process took up all of the building.
