The first stage in alluvial gold mining is to take the dredged river bed material and separate the small sand faction (where the gold is found) from the larger mineral fraction. In a typical alluvial mining process physical separation methods such as screening and gravity separation are employed to separate the gold from the mineral fraction.

Gold alloys with mercury to form an amalgam from which the gold can subsequently be separated by evaporating the mercury. The simplicity of the technique, low investment costs and its comparatively high gold recovery rate has made the mercury amalgam method an integral part of the artisanal and small scale gold mining operations.
Many artisanal and smallscale miners are achieving high rates of gold recovery without mercury, benefiting their health, the health of their communities, and the environment. On this page, we summarize some of the techniques in mercuryfree artisanal and smallscale gold mining.
Gold deposits along the general gold path can be small or large, depending upon the size of the gold trap. The most important type of gold trap in river mining is called the "paystreak". Paystreaks always form along the gold path where the river''s flow slows down on a large scale during a major flood storm.

Historically, mercury was used extensively in placer gold mining in order to form mercurygold amalgam with smaller gold particles, and thereby increase the gold recovery rates. Largescale use of mercury stopped in the 1960s. However, mercury is still used in artisanal and smallscale gold mining (ASGM), often clandestine, gold prospecting.
The transfer of skills and knowledge of alluvial gold mining took place in the 1950s and 1960s when many residents, especially around the Wau/Bulolo area, applied for and were granted MLs. By the early 1970s, most expatriates who originally held mining leases for smallscale gold mining in the country had transferred their leases to citizens.
The GravityBorax Method GBM is still unknown to most Artisanal and smallscale gold miners (ASGMs) worldwide as most still use mercury to extract gold.
