— During prolonged periods of crusher maintenance the ore walls can be bulldozed over the ore feeders to provide an uninterrupted supply of ore for milling. GRINDING COPPER ORE. As it is shown in this study the ¾" or 1″ crushed ore is fed to a rod mill operating in open circuit and discharging a product approximately minus 14-mesh.
The mill produces copper and gold concentrate from mined ore through a process to separate valuable minerals from the impurities covering them. The main steps in the process are crushing, grinding, flotation, and dewatering. Crushing and grinding transform ore size into fine sand in order to release particles containing copper and gold.
