发明名称 EXTRACTION OF MOLYBDENUM FROM SULPHIDE MATERIALS CONTAINING MOLYBDENUM BY MEANS OF BIOLOGICAL LEACHING IN PRESENCE OF IRON
摘要 FIELD: metallurgy.SUBSTANCE: method involves stages of (a) material interaction with acid leaching solution in presence at least of one iron compound and acidophilic microorganisms at least capable of oxidating ferrous iron, and (b) leaching. Leaching stage (b) is performed at control of molar ratio of dissolved ferric iron to dissolved molybdenum and it is assumed equal at least to 6:1, preferably at least to 7:1 and after leaching there performed is stage of (c) molybdenum extraction at least from one solid and liquid residue of the leaching process. Finally, molybdenum is extracted from leaching residue of leaching process. Final degree of Mo extraction from sulphide material containing molybdenum is 89%.EFFECT: effective molybdenum extraction from sulphide material containing molybdenum.24 cl, 21 dwg, 9 tbl, 10 ex
