“The country boasts of integrated beneficiation facilities for nickel, ferrochrome, and coal. For gold the country has a central smelting and refining facility in Fidelity Printers and Refiners. There are very bright prospects that the beneficiation of asbestos, iron ore, and copper will soon be re-activated,” he said.

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.
