The silver ores are found along with gold ores in some parts of India. Silver is extracted from the oreargentite (Ag2S). The process of extraction of silver is called as cyanide process as sodium cyanide solution is used. The ore is crushed, concentrated and then treated with sodium cyanide solution. This reaction forms sodium argento cyanide.
Selective reaction: It is a known fact that gold is basically a nonreactive element. Gold smelting flux helps us to take advantage of this fact in the smelting process. Flux is able to react only with the impure metals, thereby causing them to form nitrates which can separate out neatly. ... Sodium Nitrate. ... Although most Gold refining ...
