grinding size of copper ore

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 size of copper ore,Copper Ore Crushing, Grinding & Flotation - 911 MetallurgistMay 22, 2017 . The attraction of semi-autogenous grinding in copper operations is that they can accommodate ores that are hard or soft, wet or dry, sticky or otherwise. . while the regrind cyclone overflow product, which is returned to the cleaner flotation section, has been reduced in size to 90 percent minus 325 mesh.
