 · The gold mining industry has so widely accepted the use of batch centrifugal concentrators (BCC) and intensive cyanidation (IC) systems for the recovery of GRG that these may well be considered requirements of any plant processing ore containing appreciable GRG. The recovery of gold by gravity is quick, easy and cheap by comparison to alternatives.

Gravity Separation Equipment

Gravity Separation Equipment

Gravity separation is a important mineral recovery method and has been the main beneficiation sector used in gold mining plants, alternatively ahead of other processes such as flotation and cyanidation. Gravity separation is an environmentally friendly beneficiation method that relies on water flow and gravity to separate target value minerals and gangues.

Gravity Concentration in Artisanal Gold Mining

Worldwide there are over 43 million artisanal miners in virtually all developing countries extracting at least 30 different minerals. Gold, due to its increasing value, is the main mineral extracted by at least half of these miners. The large majority use amalgamation either as the final process to extract gold from gravity concentrates or from the whole ore.

Cyanidation For mining appliions and exploration, cyanide leach tests are used to establish extraction efficiency. Alternatives include cold cyanide extraction, hot extraction and pregrobbing affinity. Prerobbing of gold during cyanide leaching occurs when the leached gold is adsorbed by certain components of the ore and not recovered.
