Copper Ore Gravity Separation Processing Plant
This process is called the gravity preselection of copper ore. The purpose is to improve the grade of copper ore, discard waste rock by a large margin, and make the copper ore that was originally worthless for sorting have beneficiation value. This is also the most effective application method of gravity separation in copper ore beneficiation.
