Problems solved by technology

However, the common problems of the methods listed above are that the separation effect of various metal minerals is not good, the metal recovery rate is low, and the amount of copper and zinc mixed in lead concentrate is high, resulting in poor product quality. Some methods have high energy consumption, and some methods have high energy consumption. The method is poisonous and pollutes the environment. Therefore, people have been looking for a simple and effective separation method
This process still does not solve the problems of poor metal separation effect, low metal recovery rate, high content of copper and zinc in lead concentrates, resulting in poor product quality, etc.

Embodiment 1

[0022] The combined beneficiation method of copper-lead-zinc-tin polymetallic sulfide ore consists of primary grinding of raw ore, mixed flotation of copper, lead and sulfur, secondary grinding and selection, separation of copper, lead and sulfur, lead flotation, and zinc flotation; In the mixed flotation, the beneficiation agent ethylene butyl mixed with xanthate is used as the collector of copper and lead minerals, and zinc sulfate and sodium sulfite are used as the inhibitor of zinc minerals; in the separation of copper, lead and sulfur, sodium sulfite and sodium thiosulfate are used as the lead and sulfur Mineral inhibitor, Z-200 is used as a collector for copper mineral sweeping. Calculated on the basis of 1 ton of raw ore, the first-stage grinding -200 mesh accounts for 70%, and the second-stage grinding -400 mesh accounts for 65%. The dosage is 40g, the dosage of zinc sulfate is 700g, and the dosage of sodium sulfite is 400g; the dosage of sodium sulfite in copper-lead-...

Abstract

The invention relates to a beneficiation method, in particular to a beneficiation method for separating the polymetallic sulphide ore containing copper, lead, zinc and tin. The method comprises the following steps: (1) carrying out ore grinding on the raw ore before carrying out bulk flotation on copper, lead and sulphur, using diethyl mixed with xanthate as collecting agent of copper and lead mineral, using zinc sulphate and sodium sulfite as inhibitor of zinc mineral; (2) carrying out phase-2 ore grinding and selection; (3) separating copper, lead and sulphur, using sodium sulfite and sodium thiosulfate as the inhibitor of the lead and sulphur mineral, using Z-200 as collecting agent for separation and scavenging and then carrying out lead flotation after the separation and scavenging; (4) carrying out zin flotation on the bulk flotation tailings; and (5) finally, carrying out reselection on the zinc flotation tailings to recover tin. The metalliferous mineral of the invention has the advantages of good separating effect, high metal recovery rate, more complete comprehensive recovery of useful minerals, low cost of medicament, simple method, easy operation and energy conservation.

Description

technical field [0001] The invention relates to a beneficiation method of copper-lead-zinc-tin polymetallic sulfide ore, belonging to the technical field of beneficiation of nonferrous metal ore. Background technique [0002] There are many kinds of minerals in copper-lead-zinc polymetallic sulfide ore. Due to the close symbiotic relationship of various metals, they are interconnected and wrapped in fine particles, and the particle size of the embedded distribution is extremely uneven, and the existence of secondary copper minerals has great influence on the distribution of sulfide ores. The selection has a great influence, and the sorting is very difficult. Throughout the domestic and foreign sulfide ore concentrators, most of the processing of copper-lead-zinc polymetallic sulfide ore is to grind the ore to the required fineness, and obtain copper-lead-zinc mixed concentrate through flotation. There are three main methods for separating copper, lead and zinc from copper, ...
