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.

If the copper grade in the ore is reduced to 1%, the heap height was 9 m for all the copper prices, but the leaching times decreased (and also the recoveries) as the metal price increased. This simple example shows that there are clear ways to improve the design and planning, in order to maximize profits in heap leaching systems.

Grinding roller squashes materials on the millstone directly, which can reduce 30 or 40 percent of energy consumption. Grinding roller doesn’t contact with millstone, so the service life will be longer. Hot wind from outside will contact with powdery materials in the grinding mill directly. It can save a dryer because of high drying efficiency.
