ИСТИНА

A method for hydrometallurgical processing of manganese ore enrichment waste, involving the supply of mixed carbonate-oxidized ore enrichment waste in a 5-10% aqueous solution of sulfuric acid, intensive mixing of the suspension for 2 hours, and retention of the resulting pulp for 1 hour. hour, removal of the productive solution, its vacuum filtration and freezing, while the residues of manganese ore enrichment are separately classified carbonate or carbonate-silicate mineralogical composition, finely fractionated mechanically activated secondary raw materials with a thickness of 0-3 mm. material supplied reactively for manganese leaching, and in an aqueous solution of sulfuric acid required for chemical reduction reactions, where the initial amount of sulfuric acid is 10-15% higher than the stoichiometric amount required for manganese recovery.
