Abstract

1. Способ вскрытия молибденсодержащих руд, включающий приготовление пульпы, подкисление ее, выщелачивание в присутствии кислородсодержащего газа с подачей серной и азотной кислот и восстановителя, в качестве которого используют часть рудной пульпы, в обособленную внутри аппарата зону, отличающийся тем, что, с целью снижения содержания окислов азота в отходящих газах, перед подачей кислот и восстановителя проводят их смешение.2. Способ по п.1, отличающийся тем, что окислительно-восстановительный потенциал при подкислении поддерживают в пределах 0,45 - 0,55 В относительно хлорсеребряного электрода сравнения.1. The method of opening molybdenum-containing ores, including pulp preparation, acidifying it, leaching in the presence of oxygen-containing gas with sulfuric and nitric acid feed and a reducing agent, which is used as part of the ore pulp, in the zone separated in the apparatus, characterized in the content of nitrogen oxides in the exhaust gases, before the supply of acids and reducing agent, they are mixed. The method according to claim 1, characterized in that the oxidation-reduction potential during acidification is maintained within 0.45-0.5 V relative to the silver chloride reference electrode.
