Gold extraction Wikipedia

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 flotation processes may also be used to concentrate the gold.

GRAVITY CONCENTRATION OF GOLD FROM CYCLONE

Many process engineers view gravity concentration in gold grinding circuits as a nuisance and a security risk. In part, this is probably due to the chequered history of enhanced gravity concentration, and the inability to predict the impact a gravity circuit will have on overall performance of a given plant.
