Изобретение относитс к гидрометаллургической переработке рудиого сырь .The invention relates to the hydrometallurgical processing of ore raw materials.
Известен способ селективного выделени металлов из рудного сырь , нутем контактировани с нейтральными органическими растворител ми , нредварительно обработанными азотной кислотой.There is a known method for the selective isolation of metals from ore raw materials by contacting neutral organic solvents previously treated with nitric acid.
Недостатками известного способа вл ютс низка степень извлечени металла в органическую фазу вследствие низкой смачиваемости руды, а также низкие скорости сгуодени и фильтровани пульпы, что значительно снижает технико-экономические показатели процесса вскрыти рудного сырь .The disadvantages of this method are the low degree of metal extraction into the organic phase due to the low wettability of the ore, as well as low rates of coagulation and filtration of the pulp, which significantly reduces the technical and economic indicators of the process of opening the ore raw materials.
Более глубокое извлечение металла и повышение эффективиости сгущени обеспечиваетс введением в руду, после смешени ее с органическим растворителем, воды в количестве 4-20% ио отношению к весу сухой руды.A deeper metal extraction and an increase in the condensation efficiency is provided by introducing into the ore, after mixing it with an organic solvent, water in an amount of 4-20% relative to the weight of dry ore.
За счет этого улучшаютс услови массообмена между твердой рудной фазой и органическими растворител ми, несуш.ими вышелачиваюидий реагент, а также повышаютс скорости сгущеии и фильтровании руднойDue to this, the conditions of mass transfer between the solid ore phase and organic solvents, the decomposition of these materials, and the rate of condensation and filtration of the ore are increased.
пульпы вследствие ее частичной коагул ции.pulp due to its partial coagulation.
При выделении молибдена из руды, содержаш ,ей 0,42% его, контактироваиием ее с органическим раствором 0,2 лг. ТБФ и 0,2 м.When molybdenum is extracted from ore, it contains 0.42% of it by contacting it with an organic solution of 0.2 lg. TBP and 0.2 m.
Д2ЭГФК в сульфированном керосине, содержащем смесь азотной и серной кислот, добавление 20% (по весу к руде) воды или водного раствора электролита нозволило повысить стеиень извлечени молибдена с 81,5 до 93%.D2EHPA in sulphonated kerosene containing a mixture of nitric and sulfuric acids, adding 20% (by weight to the ore) water or an aqueous electrolyte solution did not allow to increase the molybdenum extraction rate from 81.5% to 93%.
скорость сгущени с 0,03 до 0,78 м/час и скорость фильтровани с 0,047 до 5,0 .a thickening rate from 0.03 to 0.78 m / h and a filtration rate from 0.047 to 5.0.
