METHOD OF EXTRACTING GOLD FROM CLAY PLACERS Russian patent published in 2005 - IPC

Abstract RU 2259886 C1

FIELD: separating solid materials.

SUBSTANCE: method comprises washing, disintegrating, gravitational enriching in sluice boxes of deep filling, grinding, gravitational enriching in shallow sluice boxes, washing concentrate off catching surface, and finishing concentrate. After washing and disintegrating, the clay pellets are softened in the process of transporting pulp in the pulp duct by impacting the moving clay pellets with metallic pins mounted in the bottom section of the pulp duct. The length of the metallic pins decrease downstream along the pulp duct proportional to the maximum diameter of the clay pellet.

EFFECT: increased yield of gold.
