Abstract

Research on the technology for beneficiation of sludge tails of the processing of chromite containing ore Donskoi ore mining and processing enterprise of the Republic of Kazakhstan was provided. Physical and chemical analysis of sludge tails and processing by-products was shown. The technological scheme for processing of sludge tails includes: preactivationof tails in 120 g / dm3slurry soda solution,at a liquid to solid ratio of 10 at 120 °C for 90 minutes; sulfuric acid leaching with30 %ammonium hydrosulfate solution and gravity concentration on centrifugal separator. The final chromite concentrate contained 59.2 % Cr2O3, with a recovery of 86.8 %
