Abstract
1. Способ переработки молибденсодержащих материалов, включающий обработку исходного рудного материала серной кислотой с последующим выщелачиванием в три стадии при поддержании определенного значения ОВП на первой стадии нитрат-ионами, на второй и третьей стадиях исходным рудным материалом при ОВП (на третьей стадии 700 мВ), отличающийся тем, что, с целью повышения степени извлечения молибдена, выщелачиванию на первой стадии подвергают 30 - 40% рудного материала и ведут его при ОВП 760 - 800 мВ и на второй стадии при ОВП 730 - 750 мВ.2. Способ по п.1, отличающийся тем, что обработку исходного материала серной кислотой ведут при избыточной кислотности 20 - 60 г/л.3. Способ по п.1, отличающийся тем, что на третьей стадии поддерживают значение ОВП 700 - 720 мВ.4. Способ по п.1, отличающийся тем, что выщелачивание исходного рудного материала на первой стадии ведут в присутствии 5,0 - 10,0 г/л ионов Fe.5. Способ по п. 1, отличающийся тем, что, с целью улучшения условий труда, на первой стадии выщелачивания перед введением нитрат-ионов вводят пиролюзит до достижения значения ОВП 700 мВ.1. A method of processing molybdenum-containing materials, including processing the source of ore material with sulfuric acid, followed by leaching in three stages while maintaining a certain value of AFP in the first stage with nitrate ions, in the second and third stages of the original ore material in AFP (in the third stage 700 mV) characterized in that, in order to increase the degree of extraction of molybdenum, 30 - 40% of the ore material is subjected to leaching at the first stage and is conducted at AFP 760 - 800 mV and at the second stage at AFP 730 - 750 mV.2. The method according to claim 1, characterized in that the treatment of the starting material with sulfuric acid is carried out at an excess acidity of 20 to 60 g / l. The method according to claim 1, characterized in that in the third stage, the ORP value of 700-720 mV is maintained. The method according to claim 1, characterized in that the leaching of the source ore material in the first stage is carried out in the presence of 5.0 - 10.0 g / l of Fe.5 ions. A method according to claim 1, characterized in that, in order to improve working conditions, in the first leaching stage, before the introduction of nitrate ions, pyrolusite is introduced to achieve the ORP value of 700 mV.
