Copper ore flotation process

Only the flotation process mentioned above could make this practicable; and even so, it requires large companies with huge plants, continuous working and immense capital. This explains why, in order to smelt 4 million tons of new copper in 1963, nearly 400 million tons

    Development of copper recovery process from flotation

    Jun 15, 2018 The total copper recovered from its ore through flotation process is about 56% [6,18], which indicates that the flotation tailings still contain valuable copper components such as chalcopyrite. In addition, old flotation tailings sometimes have a higher copper grade (0.2–0.4%) than that of low‒grade ores (0.2‒0.3%)

    Copper Mining and Processing: Processing Copper Ores

    This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores, in four basic steps: 1) froth flotation, 2) thickening, 3) smelting, and 4) electrolysis. Following mining, transporting, and crushing to a consistent gravel or golf ball-size, the crushed ore is further processed at a mill
