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

Abstract RU 2814041 C1

FIELD: mining.

SUBSTANCE: mineral processing can be used in the gravitational processing of technogenic gold-bearing formations with fine-grained gold. The method includes erosion of sands, their disintegration at sluices, classification of sands with the separation 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 a molten alloy of 60 wt.% Sn, 40 wt.% Bi and is evenly distributed over its surface with a layer thickness of no more than the size of the largest particle of the waste product, settle the waste product in a settling tank during the time of precipitation of gold particles. Sediment of gold particles and residual tailings of the waste product are separated from the melt of the alloy 60 wt.% Sn, 40 wt.% Bi.

EFFECT: increasing the efficiency of the gravitational processing.
