Yenbayev, I A and Rudnev, B P and Shamin, A A (2000) Processing of Discard Tailings and Non-conventional raw Materials using efficient upgrading Processes. In: International Symposium on Processing of fines. NML Jamshedpur, Jamshedpur, pp. 72-80. ISBN 81-87053-53-4
At Russian alluvial deposits , precious metals are nor-mally recovered with the aid of simple ore dressing units, such as washing slices.Particles of precious metals with a size of less than 100 um are not recovered by this method. Centrifugal apparatus and processing technology have been developed for recovery of fine and ultra fine particles of precious metals ensuring recoveries of up to 90-97% and producing a product containing 1-2% Au. This technology is environmentally sound and does not impose any nega-tive impact on the ambient environment. The tailings generated by a DM-250 dredge have a gold content front 0.5 to 1.5 g/t, of which about 85% has it particle size, of less than 50 um. The use of proposed centrifugal equipment at an alluvial operation for processing of dredge tailings made it possible to produce concentrate with a gold content of 1.1 kg /tat with a gold recovery of 92.7%.
