Artisanal and Small-Scale Gold Mining Without

This process is mostly used in large scale mining operations but has been increasingly adopted in small scale mining because of its high gold recovery rate and low cost. The best practices for chemical leaching are a combination of pre-concentration and mill leaching, as they lead to the least amount of waste, a short processing time for miners, and high gold recoveries.

SMALL SCALE GOLD MINING AND MARKETING IN

2011-10-4  The use of mercury has become popular among small scale miners because amalgamation is known to efficiently extract fine gold particles from concentrates obtained by panning or sluicing operations. Gold alloys with mercury to form an amalgam from which the gold could subsequently be separated by evaporating the mercury. The simplicity of the technique, low investment cost and its comparatively high gold recovery has made amalgam an integral part of the small scale gold mining operations.
