Problems solved by technology

At present, there is still no good separation technology for copper-lead-zinc-iron complex sulfide ores. During the separation process, the metal recovery rate is often low and the mutual inclusion is serious, resulting in poor quality of the final product.

Embodiment 1

[0018] Grind 1 ton of raw ore until the fineness is -74μm and the content is 70%, add 12kg of lime, and add 100g of ethyl xanthate after 5 minutes to carry out mixed flotation of copper, lead and zinc, which is divided into two roughing; Add 200g of activated carbon to the mixed concentrate after selection, add 1000g of zinc sulfate and 500g of sodium carbonate after 5 minutes, add 100g of BK320 and 100g of ethyl disulfide after 3 minutes for mixed flotation of copper and lead, including three times of roughing and three times of beneficiation Add 150g of activated carbon to the mixed concentrate after copper-lead flotation to remove the drug, add 300g of water glass and 300g of sodium sulfite to suppress lead minerals after 5 minutes, add 150g of Z-200 after 3 minutes, and pass three times of roughing and three times of refining Copper concentrate and lead concentrate are obtained by selection; 8kg sulfuric acid is added to the tailings after copper-lead-zinc mixed flotation t...

Embodiment 2

[0020] Grind 1 ton of raw ore until the fineness is -74μm and the content is 85%, add 4kg of lime, and add 150g of ethyl xanthate after 5 minutes to carry out mixed flotation of copper, lead and zinc, which is divided into two roughing; First add 80g of activated carbon to the mixed concentrate after selection, add 600g of zinc sulfate and 300g of sodium carbonate after 5 minutes, add 60g of BK320 and 60g of ethylsulfite after 3 minutes for mixed flotation of copper and lead, including three times of roughing and three times of beneficiation Add 50g of activated carbon to the mixed concentrate after copper-lead flotation to remove the drug, add 200g of water glass and 200g of sodium sulfite to suppress lead minerals after 5 minutes, add 100g of Z-200 after 3 minutes, and pass three times of roughing and three times of refining Copper concentrate and lead concentrate are obtained by selection; 7kg of sulfuric acid is added to the tailings after copper-lead-zinc mixed flotation t...

Embodiment 3

[0022] After grinding 1 ton of raw ore to a fineness of -74μm and a content of 90%, add 8kg of lime and 5 minutes later add 200g of ethyl xanthate to carry out mixed flotation of copper, lead and zinc, which is divided into two roughings; First add 100g of activated carbon to the mixed concentrate after selection, add 1200g of zinc sulfate and 600g of sodium carbonate after 5 minutes, add 120g of BK320 and 120g of ethyl disulfide after 3 minutes for mixed flotation of copper and lead, including three times of roughing and three times of beneficiation Add 100g of active carbon to the mixed concentrate after copper-lead flotation to remove the drug, add 400g of water glass and 400g of sodium sulfite to suppress lead minerals after 5 minutes, add 80g of Z-200 after 3 minutes, and pass three times of roughing and three times of refining Copper concentrate and lead concentrate are obtained by selection; 4kg of sulfuric acid is added to the tailings of copper-lead-zinc mixed flotatio...

Abstract

The invention discloses a mineral dressing method for separating a Cu-Pb-Zn-Fe multi-metal sulfide mineral, which comprises the following steps: selecting a raw mineral, grinding the mineral, carrying out mixed flotation to Cu, Pb and Zn, carrying out mixed flotation to Cu and Pb, separating Cu and Pb, carrying out Zn flotation and pyrite flotation, and finally obtaining a Cu, Pb, Zn and pyrite concentrate. The method has the advantages of good metal sulfide mineral effect and high metal recovery rate, is simple to operate and is suitable to popularize and apply.

Description

technical field [0001] The invention relates to a beneficiation method, in particular to a beneficiation method for separating copper-lead-zinc-iron polymetallic sulfide ore. Background technique [0002] Copper-lead-zinc-iron complex sulfide ores, due to the dense symbiosis of several metals, intercalated with fine particle size, are very difficult to sort. At present, there is still no good separation technology for copper-lead-zinc-iron complex sulfide ores. During the separation process, the metal recovery rate is often low and the metal inclusions are serious, resulting in poor quality of the final product. Contents of the invention [0003] In order to solve the defects of the prior art, the present invention provides a beneficiation method for separating copper-lead-zinc-iron-iron sulfide ore, which is aimed at a large amount of copper-iron-lead-zinc polymetallic sulfide ore resources formed due to the difficulty in separating copper, lead, zinc, iron and sulfur. C...
