Oct 28 2020· While Antarctica is also a source of copper ore deposits a long term moratorium on mining in Antarctica was established in 1991 to preserve the area Copper smelting is the process of separating copper metal from the rock in which it is naturally embedded by melting it
There are many types of copper ore found throughout the world Picture 4 shows the distribution of these deposits About 80 of all copper extracted comes from sulphide ores A typical ore contains only 0 5 to 2 0 copper It is a measure of the value of copper that it
Process steps include mining concentration roasting smelting converting and finally fire and electrolytic refining 12 3 2 Process Description2 4 Mining produces ores with less than 1 percent copper Concentration is accomplished at the mine sites by crushing grinding and flotation purification resulting in ore with 15 to 35 percent copper
At 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 2 From the formula it is clear that iron and sulphur have to be removed in order to produce copper
