Abstract | In molybdenum solutions with complicated composition there is certain background of sulfate salts, which appear at molybdenite concentrate leaching. Presence of SO42- – ions in solution negative influences on process of molybdenum trioxide sedimentation. Raise degree of molybdenum recovery into trioxide is possible by using membrane electrolysis for sulfate – ions removal into a solution. Data on sulfate – ions influence on process of molybdenum recovery are offered in given work. |

Abstract | Results of kinetics research of gold-bearing mineral – pyrite (FeS2) dissolution by cyanide and cyanide – thiosulfate solutions are presented in the work. The dissolving complex system containing along with traditional cyanide also sodium thiosulfate can be successfully applied for noble metals direct leaching from sulfide ores. The investigated method of noble metals direct leaching enables significant decrease of process’s time and stage with increase of recovery degree. Thus the degree of gold leaching by cyanide – thiosulfate solutions increases for 10% in comparison with cyanide solutions. |
Keywords | direct leaching, gold-bearing pyrite, cyanide – thiosulfate solutions |
