METHOD FOR GRAVITATIONAL EXTRACTION OF GOLD DURING PLACER BENEFICIATION Russian patent published in 2024 - IPC C22B11/00 B03B7/00 

Abstract RU 2814050 C1

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 sent to a settling tank with the alloy melt, wt.%: Ga - 67, In - 29, Zn - 4 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 a 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 said melt.

EFFECT: increasing the efficiency of the gravitational enrichment process.
