Alluvial gold is found beneath the surface at the bottom of a creak or stream. Alluvial gold mining is the process of extracting gold from these creaks, rivers and streams and is generally considered to be the most environmentally friendly method of gold mining as a result of the reduced environmental impact when compared to underground mining.

By cyaniding and carbon leaching crushed gold ore slurry simultaneously, the CIL process lowers the gold mining operation cost and increases the gold recovery rate to a degree of 99%. It has become the first choice of modern gold mining and beneficiation plant design. JXSC Mine Machinery Factory supplies EPC services to mine owners since 1985.
