Extracting Metals in the Middle of the Activity Series, Metals and Non .

A metal is obtained from its ore by the processes of reduction or by electrolysis. In the reduction process, it is the oxide ore that is reduced. It is easier to reduce an oxide ore as compared to its sulphides and carbonates. If the ore is not an oxide ore, it is first converted to the oxide by the process of calcination or by roasting.

Smelting and Roasting Ores to recover gold, silver and other metals

Some prospectors are interested in the methods of processing sulfide ores to extract their values. The two of the best known processes are smelting and roasting. The two are actually different methods, but both involve heating the ore to high temperatures. Technically, any methods which consist of processing ore by heating.
