METHOD OF EXTRACTION OF GOLD AT HYDROMECHANIZED MINING OF CLAY PLACER SANDS Russian patent published in 2005 - IPC

Abstract RU 2263153 C1

FIELD: hydromechanized mining of placers containing gold at high content of clay fraction.

SUBSTANCE: proposed method includes flushing, disintegration and treatment of pulp in the course of delivery to deep flooding sluice box in pulp-feed line by ozone-oxygen-air mixture, thus performing oxidation of medium, intensifying coagulation of mineral grains at gravitational concentration, flocculation of clay particles during treatment of water and reduction of muddiness and chromaticity of process circulating water, gravitational concentration in deep flooding sluice boxes, screening, gravitational concentration in shallow flooding sluice boxes, cleaning-up concentrate from entrapping surfaces and final treatment of concentrate.

EFFECT: increased extraction of gold at finishing-off clay placer deposits.
