Sorting process for improving beneficiation recovery rate of nonferrous metals

A technology of non-ferrous metals and recovery rate, applied in flotation, solid separation, etc., can solve the problems that old ore concentrators or small concentrators are not applicable, the rapid flotation process system is difficult to implement, and the plant conditions are high, so as to reduce the total flotation The selection time is shortened, the flotation process is shortened, and the separation index is good.

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.

Embodiment 1

[0027] Such as figure 1 As shown, the prior art lead selection plant roughing operation is equipped with 4 flotation machines, and its technological process is: the foam product of the first groove of the roughing operation and the other three grooves of the roughing operation gather together and enter the selection I operation Sorting is carried out, and the foam products of the selection I operation enter the selection operation again.

[0028] A lead-zinc ore concentrator processes 400,000 tons of lead-zinc ore per year. The main products are lead concentrate, zinc concentrate and sulfur concentrate. The gold and silver in the ore are enriched in the form of associated precious metals to the main products through flotation. middle. The concentrator adopts the process of priority selection of lead, zinc and sulfur mixed separation and separation. Among them, the process of lead selection adopts a process of first roughing, second refining and three sweeping. Zinc inhibitor...

Embodiment 2

[0030] Please refer to figure 2 and image 3 , a sorting process for improving the recovery rate of non-ferrous metal beneficiation of the present embodiment, comprising the following steps:

[0031] 1) Rough selection: Four parallel flotation machines are used for rough selection, and the raw ore pulp enters the first tank flotation machine, the second tank flotation machine, the third tank flotation machine, and the fourth tank flotation machine for separation. Separation operation, the raw ore pulp enters the separation operation of each flotation machine to obtain their respective foam products and tailings;

[0032] 2) Selection I: the foam product obtained by the rough selection of the second trough flotation machine, the foam product obtained by the rough selection of the third trough flotation machine, the rough selection and scraped foam product obtained by the rough selection of the third trough flotation machine The foam product four scraped out by the rough sele...

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...
