Problems solved by technology

Mixed separation and separation means that two kinds of ore concentrates can be produced at the same time after separation in production. This process has certain defects in the quality assurance of concentrates, and it is difficult to take into account the quality of the two concentrates at the same time.
Priority production process means that in the production process, according to the difference in ore selectivity, two kinds of concentrates are produced in sequence. In this process, because the second concentrate is suppressed first, and then activated and produced, its existence is recovered. low rate of defects

Embodiment 1

[0018] Embodiment one, as attached figure 2 As shown: the raw ore enters the No. 1 mixing tank after grinding and grading, the stirred raw ore enters the roughing of the third tank, the lead concentrate mixture produced by the roughing of the third tank enters the first tank A, and the other tailings produced by the roughing of the third tank Enter the 3rd tank A to sweep the 1st, the lead concentrate mixture produced in the 1st tank A enters the 1st tank B, the other tailings produced in the 1st tank A return to the 3rd tank for roughing, the lead concentrate produced in the 1st tank B becomes the lead concentrate product , the other tailings produced in tank 1 B return to tank 1, the zinc-sulfur concentrate mixture produced in tank 3 A sweeps 1 and enters tank 2 A to scan 2, and the other tailings produced in tank 3 A sweeps 1 and returns to tank 3 Groove roughing, other tailings produced by Sweeping 2 in 2nd trough A return to Sweeping 1 in 3rd trough A, the zinc-sulfur co...

Embodiment 2

[0027] Embodiment two, as attached image 3 Shown: Before the selected ore enters the No. 2 mixing tank, it is the same as that in Example 1. After the zinc-sulfur concentrate mixture passes through the No. 2 mixing tank, it enters into the 3rd tank A to scavenge 3, and the 3rd tank A scavenges 3 to produce other tailings Enter into slot 3 for sweeping 4, the zinc-sulfur concentrate mixture produced in slot 3 for sweeping 4 returns to slot 3 for sweeping 3, other tailings produced in slot 3 for sweeping 4 enter slot 2 for sweeping 5, and slot 2 for sweeping 5 The zinc-sulfur concentrate mixture produced returns to scavenging 4 in tank 3, other minerals and gangues produced in tank 2 scavenging 5 form tailings D, and the zinc-sulfur concentrate mixture produced in scavenging 3 in tank A enters No. 4 stirring barrel, the zinc-sulfur concentrate mixture enters No. 4 mixing tank and then enters No. 3 tank B, the zinc-sulfur concentrate mixture produced in No. 3 tank B enters No. 1...

Abstract

The invention relates to a flotation method for re-cleaning lead zinc ore and sulfur concentrate after preferable mixing separating. The flotation method comprises a conventional preferable mixing separating process for the lead zinc ore and the sulfur concentrate and further comprises the following steps: 1) feeding: pouring sulfur concentrate pulp into a mixing separating tank; 2) performing mixing separating: separating a mixed concentrate from a first tailing through mixing separating, wherein the first tailing is formed by the other ores and gangue; 3) separating two ores: performing the two-ore separation on the mixed concentrate, thereby obtaining a first concentrate and a separated tailing; 4) beneficiating the separated tailing: performing beneficiation on the separated tailing, thereby obtaining a second sulfur concentrate and a second tailing; and 5) sending the second tailing into the second step of mixing separating. According to the process, the zinc entering into the sulfur concentrate caused by an operate error can be recycled; the recovery rate of the zinc is increased by about 0.5%; the quality-improving technical processes for the two sulfur concentrates both do not generate new waste water, waste residue and waste gas; and a new factor for damaging environment is not added.

Description

technical field [0001] The invention relates to a process flow of beneficiation of lead-zinc ore, in particular to a flotation method after mixing and optimizing sulfur concentrate of lead-zinc ore. Background technique [0002] The beneficiation process for separating two different concentrates from the ore is often a mixed separation and separation production process, or a priority production process. Mixed separation and separation means that two kinds of ore concentrates can be produced at the same time after separation in production. This process has certain defects in the quality assurance of concentrates, and it is difficult to take into account the quality of the two concentrates at the same time. Priority production process means that in the production process, according to the difference in ore selectivity, two kinds of concentrates are produced in sequence. In this process, because the second concentrate is suppressed first, and then activated and produced, its ex...
