METHOD FOR CONCENTRATION OF SANDS OF NOBLE METALS OF PLACER DEPOSITS

摘要

FIELD: mining industry; concentration of sands containing gold and other noble metals. SUBSTANCE: mined bulk after disintegration and separation of boulders and coarse gravel is concentrated on washing device with concentrate separated, and tailings are subjected to sizing to separate water with fine fraction. Then water is clarified on thickener and used as circulation water, and thickened pulp is directed for hydrometallurgical treatment. Coarse fraction of classifier is additionally washed with water which is also clarified on thickener and deposit is subjected to hydrometallurgical treatment. EFFECT: higher efficiency. 3 cl
