Gravity Concentration in Artisanal Gold Mining

Gravity concentration by jigging has been used in conventional mining operations for more than 100 years (Abols and Grady, 2006 ), but they are not common in AGM operations. Jigs have been used for gold concentration since the Old Egyptian times (Sampaio and Tavares, 2005) . Jigging is a continuous gravity concentration process that separates heavy from lighter particles by a pulsating flow of water

The myth of gravity concentration to eliminate mercury

This article highlights how gravity concentration can reduce the amount of material to be amalgamated or treated thermally or chemically to extract gold from concentrates. However, it also acknowledges that this process has the potential to eliminate the use of mercury in very rare, specific cases.

Gravity Concentration - an overview ScienceDirect Topics

In the various gold rushes of the nineteenth century, many prospectors used gold panning as a means to make their fortune—another ancient method of gravity concentration. Gravity concentration, or density-based separation methods, declined in importance in the first half of the twentieth century due to the development of froth flotation, which allowed for the selective treatment of low-grade complex ores.
