METHOD FOR EXTRACTION OF MERCURY AND GOLD FROM INTERMEDIATE PRODUCTS AND CONCENTRATION WASTES

摘要

FIELD: reprocessing of tailings. SUBSTANCE: method involves treating basic materials with reactants: liquid glass 3-4 kg/t, sodium humate 2-3 kg/t, with solid-liquid ratio being equal to 1:(3-4); conducting separation in conical hydraulic catcher by particle density in suspension; removing burden by discharging upper portion; concentrating heavy fraction on concentration plate. EFFECT: increased efficiency in extracting mercury and gold. 1 tbl
