it is much easier to extract metals from their oxides because you can easily perform a redox reaction with the metal's oxide by adding carbon and then heating it. the carbon will react with the oxygen in oxide and form co2 and hence make the metal purer than before. 1 comment.

A number of different methods can be used to separate gold from its ore, but one of the more common methods is called gold cyanidation. In the process of gold cyanidation, the ore is crushed and then cyanide ((text{CN}^{})) solution is added so that the gold particles are chemically separated from the ore. In this stage of the process, gold ...

In pyrometallurgy, an ore is heated with a reductant to obtain the metal. Theoretically, it should be possible to obtain virtually any metal from its ore by using coke, an inexpensive form of crude carbon, as the reductant. An example of such a reaction is as follows: () C a O ( s) + C ( s) → Δ C a ( l) + C O ( g) Unfortunately, many ...
