Gold ores can also be treated with potassium cyanide (KCN) or some other kind of cyanide. The gold combines with the cyanide to form a new compound, gold cyanate. The gold cyanate is then treated with an active metal, such as zinc. The active metal replaces gold in the compound, leaving pure gold.

Metallurgy - GitHub Pages

Because the density of gold (19.3 g/cm 3) is so much greater than that of most silicate minerals (about 2.5 g/cm 3), silicate particles settle more slowly and can be poured off with the water, leaving dense gold particles on the bottom of the pan. Conversely, in flotation, the compound of interest is made to float on top of a solution. Blowing air through a suspension of the crude ore in a ...

Ores are often oxides, carbonates or sulphides because these non-metals readily combine with many metals. e.g. iron + oxygen ===> iron oxide ores. Fe + O 2 (air) ===> Fe 2 O 3 or Fe 3 O 4 (not balanced equations, just the idea!) This the typical chemistry involved in metal ore formation.
