Process Introduction:
Copper ore is divided into sulfide ore (oxidation rate less than 10%), oxidized ore (oxidation rate greater than 30%) and mixed ore (oxidation rate 10%-30%) According to the different oxidation rates. the cooer ore beneficiation method is mainly with flotation method. and some with gravity method. In general, copper sulfide ore and easy-t-select mixed copper ore are treated by flotation. For difficult-to-select mixed copper ore and difficult-to-select copper oxide ore, use hydrometallurgy or flotation and hydrometallurgy combined methods.
Copper ore is generally an aggregate composed of copper sulfide or oxide and other minerals, which react with sulfuric acid to produce blue-green copper sulfate. The industrial minerals of copper include natural copper, chalcopyrite, chalcocite, tetrahedrite, chalcocite, malachite, etc.
According the copper oxide rate, copper ore can divide into ore sulfide(less than 10% copper oxide) ,ore oxide(more than 30% copper oxide) and mixing ore(10%-30% copper oxide). The main process for copper ore is flotation, for refractory mixed copper ore and refractory oxide ore, normally use the hydrometallurgy process.
As a commonly used process for copper ore beneficiation, flotation can be used for the separation of copper sulfide and oxidized copper ores. The main process of copper ore flotation is rough as follows: ore crushing and screening → stage grinding stage flotation → concentration and dehydration → copper concentrate.
