How to Process Copper Ore: Beneficiation Methods and

2021-10-28  Copper ore beneficiation methods. Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm.

Extracting copper from copper(II) carbonate Experiment

Malachite is a copper ore consisting mainly of basic copper(II) carbonate, CuCO3.Cu(OH)2. In this experiment, students learn how to produce copper from copper(II) carbonate by heating it to produce copper(II) oxide, which is then reduced to the metal using carbon as a reducing agent.

Particle damage and exposure analysis in HPGR crushing

2011-10-1  Highlights Copper ores (copper oxide ore and copper sulfide ore) were crushed by a jaw crusher and by HPGR. Crushed and sized products were evaluated for particle damage and copper grain exposure by X-ray computed tomography. Column leaching was done to determine the rate and extent of copper recovery. HPGR crushed products have more particle damage and higher copper recoveries.
