Аннотация: Taking into consideration the current depletion of the ore reserves that contain noble metals, the pressing question of man-caused wastes (flotation tailings, refinery debris, slags, etc.) involvement into processing is becoming more and more important. This type of raw material is complex in processing, demanding for improvement oПоказать полностьюf the existing beneficiation flowsheets. The article presents the results of two refinery silver-containing slag samples laboratory studies, conducted with a view to study the material composition of the samples and develop a tech- nology for recovery of noble metals from such samples. The material composition was studied using the state-of-the-art equipment - micro- scopes Axioskop 40, Hitachi TM-1000, Hitachi OI-3000. Beneficiation flowsheets with application of pneumatic and magnetic separators, centrifugal jigging machine Kelsey, flotation machine, screw strake, concentrating tables SKO and Gemeni, centrifugal separators «Itomac» and Falcon are implemented into practice. Combination gravity-flotation flowsheets are proposed for recovery of noble metals, permitting to recover gold, silver and platinum group metals into concentrated products from the studied samples: from the first sample - respective recov- ery being 87.89, 92.55 and 89.56 %, and from the second sample - 74.41, 64.9 and 78.3 %, respectively.
