Sorting process for improving beneficiation recovery rate of nonferrous metals

Abstract

The invention discloses a sorting process for improving the beneficiation recovery rate of nonferrous metals. According to the sorting process, under the conditions that original flotation equipment conditions and the plant layout are not changed and the types of the beneficiation reagents and the usage amount are unchanged, the internal structure of the original process flow of the beneficiationplant is optimized, a float product obtained through a first tank flotation machine in roughing operation of flotation target minerals is directly used as the foam product of the concentration operation I to enter the concentration operation II to undergoes sorting so that a part of easy-to-float target minerals can enter the next operation preferentially, the circulation amount of the previous concentration operation can be reduced , the flotation time can be shortened, the sorting out of the target minerals which are easy to float can be realized, and finally the recovery rate of the concentrate products can be improved.

Description

technical field [0001] The invention relates to a nonferrous metal beneficiation method, in particular to a sorting process for improving the recovery rate of nonferrous metal beneficiation. Background technique [0002] The rapid flotation process is to make full use of the difference in floatability of useful minerals, so that the useful minerals that have been dissociated and have good floatability are quickly sorted out in a short period of time to obtain high-quality concentrate products. The idea of ​​being able to produce early and quickly can shorten the flotation time, avoid over-crushing of the dissociated minerals, and can reduce the amount of circulation and metal loss in the middle of the flotation operation, thereby improving the recovery rate of the target minerals. The rapid flotation process used in the concentrator needs to adopt a separate rapid flotation process system based on the original process, which has specific requirements for the layout of the pl...

AI Technical Summary

Problems solved by technology

The rapid flotation process used in the concentrator needs to adopt a separate rapid flotation process system based on the original process, which has specific requirements for the layout of the plant and high requirements for the conditions of the plant. It is necessary to add a flotation machine and a foam scraping device , the cost of electricity increases, the flotation process is prolonged, and the intensity of system transformation is high

[0003] In the existing technology, the rapid flotation process is often difficult to implement due to the limited layout of the plant, and it is not suitable for the old or small concentrators that have been transformed.
