Afterwards mercury is added to the rock dust. Gold has the property that enables it to join to the surface of the mercury. Get a metal bin or tray, and put the circuit boards into it. Break the boards into smaller pieces so they burn faster. [8] 3. Light the boards on fire. Pour a bit of gasoline over the pieces to put the pieces on fire. Turn the burning pieces over using steel tongs, and wait until the boards are burnt black.Gold is generally found in two types of deposits: lode (vein) or placer deposits; the mining technique used to extract the gold depends upon the type of deposit. Once extracted, the gold is refined with one of four main processes: floatation, amalgamation, cyanidation, or carbon-in-pulp.Gold is widely distributed throughout the world. Tiny quantities occur in most rocks and soils. Usually, however, the amount of gold is so minute that the cost of extracting it would exceed its value. Where gold occurs in higher concentrations, the deposits are of two basic types鈥攙eins, or lodes, of gold-bearing ore, and placer deposits.R-OH+Au (CN)2-鈺怰-Au (CN)2+OH-. Gold extraction process flow.
