Ball Mill VS Rod Mill - Xinhai
Apr 7, 2016 ... For details, the grinding theory of ball mill and rod are different in many ways. For ball mill, the grinding force of steel ball to ore is less than the impact, because the contact area is small between balls and mineral. Thus, the throwing motion of ball can produce a large impact, but it need a high rotate speed...Read More
Copper - Department of Energy
Benches are cut into the walls of the mine to provide access to progressively deeper ore as upper-level ore is depleted. Ore is removed from the mine and transported to beneficiation plants for milling and concentrating. The concentrate is then smelted and refined. Open-pit mining is the primary domestic source of copper.Read More
