Abstract

Способ извлечения молибдена из руд, включающий стадийное выщелачивание серной и азотной кислотами в присутствии окислителей, отличающийся тем, что, с целью повышения степени извлечения молибдена и удешевления процесса за счет устранения с поверхности оборудования твердых отложений на основе сульфата кальция и двуокиси кремния, на первой стадии выщелачивание ведут в течение 20 - 50 мин при поддержании кислотности 0,5 - 4,0 г/л и при отношении суммарной концентрации сульфат-бисульфат ионов к концентрации нитрат-ионов 20 - 40.A method of extracting molybdenum from ores, including stepwise leaching of sulfuric and nitric acids in the presence of oxidizing agents, characterized in that, in order to increase the degree of extraction of molybdenum and reduce the cost of the process by eliminating solid deposits based on calcium sulfate and silica from the equipment surface leaching is carried out for 20 to 50 minutes while maintaining the acidity of 0.5 to 4.0 g / l and with the ratio of total concentration of sulfate bisulfate ions to the concentration of nitrate ions 20-40.
