Abstract

The invention provides a preliminary separation device for tungsten in scheelite. The preliminary separation device comprises a heating reaction tank; the grinding box body is arranged in the heating reaction tank, and a liquid accommodating cavity is formed between the grinding box body and the heating reaction tank; the grinding box body comprises a first box body and a second box body, the first box body is rotatably arranged at the top of the second box body, and a filter screen plate is arranged at the end, close to the first box body, of the second box body; the second grinding mechanism is arranged in the second box body; a plurality of filter holes are formed in one side wall of the second box body; the other side wall of the second box body is connected with a return pipe, and one end of the return pipe is communicated with the liquid accommodating cavity; a liquid outlet is formed in one side of the bottom of the liquid accommodating cavity; a discharging opening is formed in the bottom of the second box body and extends out of the heating reaction tank. The device can realize continuous separation and extraction of scheelite and improve the extraction efficiency.

Description

technical field [0001] The invention relates to the field of separation equipment, in particular to a preliminary separation device for tungsten in scheelite. Background technique [0002] Scheelite is a main raw material for refining tungsten, and its main component is CaWO 4 , and also contains impurities such as calcium oxide, iron oxide, and silicon dioxide. When refining and producing tungsten, the scheelite is usually ground and pulverized to a fine powder of about 200-300 mesh, and then the pulverized scheelite fine powder is mixed with the extraction solution, reacted, and filtered to obtain a preliminarily separated solution. [0003] At present, in the process of using scheelite to extract tungsten, it is difficult to achieve continuous extraction of scheelite, and the grinding and extraction processes cannot be carried out at the same time, resulting in low extraction efficiency and waste of extraction raw materials. SUMMARY OF THE INVENTION [0004] In order...
