Abstract

1. Способ переработки молибденовых руд, содержащих цветные и редкие металлы, включающий выщелачивание их серной кислотой в присутствии азотсодержащих реагентов - солей азотной и азотистой кислот, извлечение ценных компонентов из жидкой фазы выщелоченной пульпы с последующей ее нейтрализацией, отличающийся тем, что, с целью снижения расхода азотсодержащих реагентов и улучшения условий труда, на стадию выщелачивания дозируют оксиды и/или гидроксиды трех- и четырехвалентного марганца.2. Способ по п.1, отличающийся тем, что оксиды и/или гидроксиды марганца дозируют в количестве 10 - 40% (в пересчете на марганец) от массы азотсодержащих реагентов (в пересчете на азотную кислоту).3. Способ по пп.1 и 2, отличающийся тем, что соотношение массы марганца (IV) с массой марганца (III), дозируемых на выщелачивание, составляет (1 - 2) : 5.1. A method of processing molybdenum ores containing non-ferrous and rare metals, including leaching them with sulfuric acid in the presence of nitrogen-containing reagents - salts of nitric and nitrous acids, extraction of valuable components from the liquid phase of leached pulp with its subsequent neutralization, characterized in that, in order to reduce consumption of nitrogen-containing reagents and improvement of working conditions; oxides and / or hydroxides of trivalent and tetravalent manganese are dosed to the leaching stage. The method according to claim 1, characterized in that the manganese oxides and / or hydroxides are metered in an amount of 10-40% (in terms of manganese) of the mass of nitrogen-containing reagents (in terms of nitric acid). The method according to claims 1 and 2, characterized in that the mass ratio of manganese (IV) with the mass of manganese (III), dosed for leaching, is (1 - 2): 5.
