Gold extraction

Gravity concentration has been historically the most important way of extracting the native metal using pans or washing tables. Amalgamation with mercury was used to enhance recovery, often by adding it directly to the riffle tables, and mercury is still widely used in small diggings across the world. However, froth flotationprocesses may also be used to concentrate the gold. In some cases, particularly when the gold is pr

extracted through a cyanide leaching and carbon adsorption process. A high-grade gold solution is then produced for electrowinning which is followed by smelting to create doré bars. Doré is a semi-pure alloy of gold and silver. Gold by nature is very dense (19.3x denser than water and 7.3x denser than quartz) and malleable, causing it to grind slowly. These properties cause gold particles to
