Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore 0.2.
4C. Purification of Copper by Electrolysis extraction from ore above. The impure copper from a smelter is cast into a block to form the positive anode.The cathode is made of previously purified copper.These are dipped into an electrolyte of copperII sulphate solution. When the d.c electrical current is passed through the solution electrolysis takes place.
Malachite is a copper ore consisting mainly of basic copperII carbonate, CuCO3.CuOH2. In this experiment, students learn how to produce copper from copperII carbonate by heating it to produce copperII oxide, which is then reduced to the metal using carbon as a reducing agent.

Jun 23, 2016 An intensified oxidative acid leaching of coppercadmium-bearing slag featuring using high-efficient oxygen carrier, such as activated carbon, was investigated to achieve high leaching rate of valuable metals. The effects of leaching variables, including agitation rate, sulfuric acid concentration, temperature, slag particle size, activated carbon and cupric ion concentration, were examined.
The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. The sulphur dioxide escapes the copper and this causes bubbles to appear and burst as SO2 leaves.
