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.
