Miners then process the copper or nickel ore to find cobalt by crushing the ore in primary cone crushers, using wet magnetic separators to separate the copper or nickel, and reducing it to mesh in a ball mill, which is a mineral grinder. Cobalt Extraction. Cobalt is then extracted in a variety of ways.
The unwanted waste rock (gangue) falls to the bottom and is removed. The froth is skimmed off the surface and the enriched ore (mainly the copper mineral) is taken away for roasting. The mixture of water, ing agent and paraffin is recycled. After this stage the enriched ore now contains about 25% copper by mass.
Stage 3: Roasting At this stage of the process, the chemical reactions begin. They convert the copper minerals into copper metal. We can illustrate the types of process using the example of chalcopyrite – CuFeS 2.From the formula, it is clear that iron and sulfur have to be removed in order to produce copper.
In each of these mining methods, various earth-moving equipment including shovels, dozers, hauling trucks, and loaders are used to remove and transport the ore.
