Copper mining. The main stages.

This is not enough to make it commercially viable to extract the rock. Copper mines are only set up where there is more than 5kg of copper per tonne of rock (0.5% by mass). Ideally, the figure should be closer to 2%. The flow chart shows you how copper is extracted from its ore and converted into pure metal.

Principle of Electrolysis of Copper Sulfate Electrolyte

Feb 24, 2012 · Whenever copper sulfate or CuSO 4 is added to water, it gets dissolved in the water. As CuSO 4 is an electrolyte, it splits into Cu + + (cation) and SO 4 − − (anion) ions and move freely in the solution.. Now we will immerse two copper electrodes in that solution. The Cu + + ions (cation) will be attracted towards cathode i.e. the electrode connected to the negative
