Embodiment 1

[0040]The raw ore of this embodiment is taken from a certain silver-containing copper-lead-zinc polymetallic sulfide ore in Inner Mongolia. t, the mass percentage of sulfur is 6.12%. Process flow chart such as figure 1 As shown, the beneficiation steps are as follows:

[0041] S1. Raw ore is ground to -0.074mm at one time, accounting for 42%;

[0042] S2. The ore pulp after the primary grinding in step S1 is subjected to copper-lead-silver mixed flotation, calculated on the basis of 1 ton of raw ore, in the copper-lead-silver mixed flotation, sodium carbonate and zinc sulfate are combined as regulators in a mass ratio of 1:1, and the combined amount It is 2600 grams, adjust the pulp pH value to be 9, and the dosage of ammonium butyl ammonium black medicine is 40 grams; Obtain copper-lead-silver mixed concentrate and copper-lead-silver mixed flotation tailings respectively;

[0043] S3. The copper-lead-silver mixed concentrate obtained in step S2 is subjected to secondary gr...

Embodiment 2

[0049] The raw ore of this embodiment is taken from a certain silver-containing copper-lead-zinc polymetallic sulfide ore in Yunnan. t, the mass percentage of sulfur is 10.96%. Process flow chart such as figure 2 As shown, the beneficiation steps are as follows:

[0050] S1. Raw ore is ground to -0.074mm at one time, accounting for 80%;

[0051] S2. The ore pulp after the primary grinding in step S1 is subjected to copper-lead-silver mixed flotation, calculated on the basis of 1 ton of raw ore, in copper-lead-silver mixed flotation, sodium carbonate and zinc sulfate are combined as regulators in a mass ratio of 4:1, and the combined amount It is 2500 grams, adjust the pulp pH value to be 9, and the dosage of butylammonium black medicine is 50 grams; Obtain copper-lead-silver mixed concentrate and copper-lead-silver mixed flotation tailings respectively;

[0052] S3. The copper-lead-silver mixed concentrate obtained in step S2 is directly subjected to copper-silver mixed fl...

Embodiment 3

[0058] The raw ore of this embodiment is taken from a certain silver-containing copper-lead-zinc polymetallic sulfide ore in Yunnan. t, the mass percentage of sulfur is 11.25%. The beneficiation steps are as follows:

[0059] S1. Raw ore is ground to -0.074mm at one time, accounting for 70%;

[0060] S2. The ore pulp after the primary grinding in step S1 is subjected to copper-lead-silver mixed flotation, calculated on the basis of 1 ton of raw ore, in copper-lead-silver mixed flotation, sodium carbonate and zinc sulfate are combined as regulators in a mass ratio of 1:1, and the combined amount It is 3000 grams, adjust the pulp pH value to be 9, and the dosage of butylammonium black medicine is 50 grams; Obtain copper-lead-silver mixed concentrate and copper-lead-silver mixed flotation tailings respectively;

[0061] S3. The copper-lead-silver mixed concentrate obtained in step S2 is secondarily ground to -0.043mm and accounts for 75%, and then copper-silver mixed flotation ...

Abstract

The invention discloses a silver guidance, recovery and beneficiation method in a copper-lead-zinc sulfide ore separation process. The method provided by the invention comprises the steps of selecting raw ore; grinding the ore; bulk-flotating copper, lead and silver; bulk-flotating copper and silver; bulk-flotating lead and silver; bulk-flotating zinc and sulfur; and separating zinc and sulfur, so that an adjusting agent and a collecting agent are further optimized, and finally a copper-silver concentrate, a lead-silver concentrate, a zinc concentrate and a sulfur concentrate are finally obtained. According to the method provided by the invention, not only is a copper-lead-zinc sulfide ore separation effect good, but also the silver recovery rate in the copper-lead concentrate is greatly improved, the comprehensive utilization rate of silver resources applied in mine enterprises is greatly improved, and the economical benefit is remarkable.

Description

technical field [0001] The invention relates to the technical field of mineral processing, and more specifically, relates to a silver-directed recovery method in the separation process of copper-lead-zinc sulfide ore. Background technique [0002] Copper-lead-zinc sulfide ores are also called complex polymetallic sulfide ores. In addition to copper, lead, zinc, and sulfur sulfide minerals, this type of ore is often accompanied by a large amount of silver minerals, which is the main source of silver reserves in my country. When sorting this kind of ore, in addition to obtaining concentrates of copper, lead, zinc or sulfur, some associated silver components in the ore can also be selected as separate concentrate products, and some are enriched during the beneficiation process. In the above-mentioned main element concentrate, it will be recovered in the next step of smelting. [0003] However, according to the difficulty of silver extraction technology in the smelting process,...
