  • Hydrometallurgical Copper Extraction Process

    These crystals are washed, dried and fed to a fluidized bed where hydrogen reduction takes place, copper nodules are produced which are suitable for melting, fireThe copper oxide minimum minerals are dissolved by the acid to give a blue copper rich solution mainly of copper sulfate This solution is tapped off from the bottom of the pad and placed into big tanks with steel plates an electrical current is passed from the tank to the steel which is then electroplated with pure copperCopper Mining & Extraction Process Flow ChartOne reaction that takes place is: 2CuFeS2(s) + 3O2(g) → 2FeO(s) + 2CuS(s) + 2SO2(g) As SO2is hazardous, it has to be removed from the gases released into the environment One way of solving the problem is to convert it to sulphuric acid This is a valuable byproduct and helps to offset the costs of copperCopper mining Chemical reactions

  • Copper mining and the copper extraction process

    The process includes the following stages: The copper ores are mechanically crushed and ground The resulting mixture is treated using flotation with air injection and agitation to leave concentrates containing around 30% copper The concentrates are fed to a smelter to remove most of the iron and sulphur and then to a converter which is usedAt 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 2From the formula, it isCopper mining Chemical reactionsThe copper is then recovered by electrolysis This process is known as SXEW (solvent extraction/electrowinning) Advantages of these processes are: Much less energy is used than in traditional mining No waste gases are given off LowProcesses extraction, mining, smelting, refining
