Abstract | FIELD: mining industry. SUBSTANCE: method is intended for producing concentrate from gold-bearing ores. According to method, primary ore is initially crushed, then crushed ore is screened to produce 30 mm size fraction, after that ore fraction smaller than 30 mm is disintegrated in roller mills, and disintegrated material is conditioned with adding water and subsequent screening to produce fraction size of 0.5 mm. Material with particle size less than 0.5 mm is classified in hydraulic cyclones. Sands from hydraulic cyclones are directed to centrifugal benefication for production of concentrate which is brought for final treatment. Tailings are disintegrated in closed cycle with hydraulic cyclones for obtaining material with particle size smaller than 0.074 mm which is subjected to benefication in centrifugal apparatus. Concentrate from centrifugal apparatus is directed to retreatment. Discharge from classification hydraulic cyclones with particle size smaller than 0.5 mm is subjected to dewatering to produce concentrate which is also directed to retreatment. Application of aforesaid method allows for increased production of concentrate from gold-bearing ores of deposit. EFFECT: higher efficiency. 4 cl |
