The world reserves of bismuth containing ore stands at 320,000 tonnes and the reserve base is estimated to be 680,000 tonnes. The mined bismuth content production in 2013 can be seen in the table below. In 2013, worldwide total bismuth mining production was 7,600 tonnes, falling 0.7% (600 tonnes) compared with last year's figure of 8,200 tonnes.Web

Removal of arsenic, antimony and bismuth from copper may take place in the smelting operations by scorification, volatilization, or, under special treatment, by processes of concentration. Owing to the great variety of materials that are treated in economical metallurgy, it is rarely possible to obtain exact weights from any particular operation.Web

Abstract. The Knelson concentrator (KC) is widely used in gold ore and other precious metal ore processing technology because of its excellent separation performance. The development history and types of KCs are reviewed in this paper. Research on the separation mechanism and characteristics of KCs was analyzed and discussed, …Web
