FIELD: gold mining.
SUBSTANCE: invention relates to the beneficiation of mineral resources and can be used in the gravitational beneficiation of technogenic gold-bearing formations with thin gold. The method includes erosion of sands, their disintegration at sluices, classification of sands, with the release of waste product and fine material containing gold, subsequent enrichment of fine material containing gold. The waste product is directed into a settling tank with a molten Wood's alloy and evenly distributed over its surface with a layer thickness of no more than the size of the largest particle of the waste product, the waste product is held in the settling tank during the time of sedimentation of gold particles. Sediment of gold particles and residual tailings of the waste product are separated from the mentioned alloy melt.
EFFECT: increasing the efficiency of the gravitational enrichment process.
