Abstract

The invention discloses a beneficiation method for cu-pb-zn polymetallic ores, and belongs to the technical field of non-ferrous metal beneficiation. According to the technical scheme, the characteristic of complex cu-pb-zn-sulfur polymetallic ores with embedded fine-grained carbon level is utilized, a technological process of carbon-removing, cu-pb partial bulk flotation, cu-pb separation and zn-and-sulfur choosing in tailings is adopted, a concentration and fine grinding mode is adopted to achieve deep reagent removal, the influence of slurry on flotation is effectively eliminated, efficient collectors A8 and depressors T721 for cu-pb separation are used in the cu-pb partial bulk flotation process, separation and recovery of copper, lead, zinc and sulfur are effectively achieved, and concentrate mixing is obviously lowered.

Description

technical field

[0001] The invention belongs to the technical field of non-ferrous metal beneficiation, and relates to a beneficiation method of copper-lead-zinc polymetallic ore. Background technique

[0002] Copper-lead-zinc complex sulfide ore, due to the dense symbiosis of several metals, the fine particle size intercalated with each other, it is very difficult to sort; the treatment of this kind of ore at home and abroad is generally to grind the ore to the required fineness, and obtain copper, lead and zinc through flotation. Mix the concentrate, and then separate the copper, lead and zinc minerals; the main disadvantage of this process is that after the copper, lead and zinc minerals are mixed and flotation, it is difficult to remove the drug and the separation effect is poor.

[0003] There are three main beneficiation methods for separating copper, lead, and zinc from copper-lead-zinc mixed concentrate. One is the heating method, which means that various chemicals o...
