Problems solved by technology

[0002] In the traditional process of lead-zinc ore flotation operation, the conventional method is to obtain part of the concentrate and tailings through one roughing; the tailings go through more than one sweeping process, and finally obtain the most demanding process that meets the grade requirements. Concentrate; but in the case of high-grade raw ore, the single roughing operation load is high, the enrichment ratio and enrichment efficiency are low, and it will increase the burden of subsequent tailings sweeping

Embodiment Construction

[0013] see figure 1 , the mixing tank 1 for pulp mixing flows out of two pipelines respectively equipped with gate valve I4 and gate valve II5, one pipeline leads to the flotation machine 2 of zinc roughing I, and the other pipeline leads to flotation machine 3 of zinc roughing II; The concentrate outlet of flotation machine 3 of zinc roughing II is equipped with gate valve III7 and gate valve IV8 respectively through tee 6, gate valve III7 is connected to flotation machine 2 of zinc roughing I through pipeline 12, and gate valve IV8 is connected to the final concentrate. The specific process is as follows.

[0014] ①The raw ore for flotation is high-grade extremely rich lead-zinc sulfide raw ore (with more than 6.5% lead, more than 15.5% zinc, industrial grade lead 1.0%, zinc 2.0%) firstly through the lead-sulfur mixed flotation process to separate lead and Sulfur, resulting in a mixture of sphalerite and gangue;

[0015] ② Add activator CuSO to the mixture of sphalerite an...

Abstract

The invention relates to an ore dressing method, in particular to a high-grade blende flotation method. The method comprises the main steps that (1) after being subjected to slurry mixing by a stirring bucket, high-grade blende is divided into two paths to flow into slurry pipes for first roughing operation and second roughing operation; and (2) the first roughing operation and the second roughing operation adopt batch flotation, and zinc concentrate is obtained by combining produced concentrate. As for the high-grade blende, the lead content is 6.5% or over, the zinc content is 15.5% or over, and the zinc concentrate grade is 51.0% or over, specifically, the grade lead content of the lead zinc ore industry is 1.0%, and the zinc content of the lead zinc ore industry is 2.0%. The controllable division method is adopted specific to the problem that the grade of selected ore fluctuates severely, the amount of ore pulp for operation is adjusted according to the grade of selected raw ore, the problem that single roughing operation is high in load and low in concentration ratio is solved, the concentrate grade meeting the technical requirements is obtained, the metal recovery rate is increased, and the grading speed of target minerals is increased.

Description

technical field [0001] The invention relates to a beneficiation method, in particular to a high-efficiency flotation method for high-grade sphalerite. Background technique [0002] In the traditional process of lead-zinc ore flotation operation, the conventional method is to obtain part of the concentrate and tailings through one roughing; the tailings go through more than one sweeping process, and finally obtain the most demanding process that meets the grade requirements. Concentrate; but in the case of high-grade raw ore, the single roughing operation load is high, the enrichment ratio and enrichment efficiency are low, and it will increase the burden of subsequent tailings sweeping. Therefore, it is necessary to provide a beneficiation process that can adapt to large changes in the grade of the selected raw ore. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a beneficiation method to adapt to the situation ...
