Smelting And Roasting Ores To Recover Gold Silver And

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 it are called pyrometallurgy. The old timers took advantage of the chemical instability of sulfides by simply heating (or roasting) them to burn off the sulfur.
