【 摘 要 】

This article illustrates the results of the study of leaching the resistant industrial products of manganese with the subsequent deposit of Mn from the solution with ammonia and hydrogen peroxide oxidizer. The chemical beneficiation of industrial products under optimal conditions aids in converting 96-98% manganese and its attendant iron into concentrates (in the form of sediments) containing 30.53-40.44% Mn and 10-15 % Fe, sludge cakes containing 80.36-83.81 % SiO2. It shows that the use of hydrometallurgy in combination with the beneficiation of hematitebraunite ores using gravity and magnetic radiation aids in the 10.39% increase of total manganese recovery in mineral form, (with 76-87.19 % increase in chemical form) and allows for integrated use of valuable components.
