A method for beneficiation and separation of copper-zinc sulfide ore

Abstract

The invention relates to a method for beneficiation and separation of copper-zinc sulfide ore, which belongs to the field of mineral processing. The specific method is as follows: the ore containing copper-zinc sulfide ore is ground and classified, and mixed flotation to obtain copper-zinc mixed concentrate; the copper-zinc mixed concentrate is processed by a vertical stirring mill, and the mixed concentrate pulp after the vertical mill treatment is thickened Dehydration treatment, the dense overflow returns to the copper-zinc mixed roughing step, while the dense underflow is slurried and stirred, and the material after slurred is transported to the flotation column for aerated flotation, so as to realize the separation of sphalerite and sphalerite in the copper-zinc mixed concentrate. Other mineral separation purposes. Compared with the traditional process for suppressing zinc by floating copper, the method of the present invention has the advantages of short process, few types of chemicals, low mutual content of concentrate products, etc., and has wide industrial application prospects.

Description

A kind of method for beneficiation and separation of copper-zinc sulfide ore technical field [0001] The present invention relates to the field of mineral processing, and specifically provides a method for beneficiation and separation of copper-containing zinc sulfide ore. Background technique [0002] The copper-containing zinc sulfide ore ores are mostly produced in hydrothermal filling metasomatism and skarn-type deposits. The peculiar lithogenesis and mineralization of the deposit lead to the extremely complex ore structure and structure of the common copper-zinc sulfide deposits at home and abroad. Miscellaneous, some ores are filled with fine-grained chalcopyrite and sphalerite and are filled with each other in the shape of veinlets, interwoven network veins or wrapping In the intergranular or fissures of pyrite, the dissociation and flotation separation of copper-zinc minerals in this type of ore are extremely difficult. In the process of ore grinding, the Cu bet...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a method for beneficiation and separation of copper-zinc sulfide ore, which overcomes the serious loss of metal resources, long process flow, and grinding cost in the traditional copper-zinc separation process of using the copper-floating zinc suppression process. For high-level defects, the separation of copper-zinc sulfide ores is realized by using flotation columns to reselect different sulfide ores, and copper sulfate is used to increase the floating rate of sphalerite to achieve the purpose of floating zinc and suppressing copper, thereby improving the efficiency of copper-zinc beneficiation and separation
