Description

Technical Field

[0001] The utility model relates to the technical field of nonferrous metal beneficiation, in particular to a flotation separation device for copper, lead and zinc ores. Background Art

[0002] Copper-lead-zinc complex sulfide ores are very difficult to separate due to the dense coexistence of several metals and the fine interpenetration of the particles. Such ores are generally processed at home and abroad by grinding the ores to the required fineness, obtaining a copper-lead-zinc mixed concentrate through flotation, and then separating the copper-lead-zinc minerals. The main disadvantage of this process is that after mixed flotation, it is difficult to remove the copper-lead-zinc minerals and the separation effect is poor. Based on this technical problem, publication number CN104437818A discloses a beneficiation method for copper-lead-zinc polymetallic ores, which belongs to the technical field of non-ferrous metal beneficiation. The adopted technical scheme is based on the property characteristics of complex copper-lead-zinc-sulfur polymetallic ore with carbon-containing fine-grained distribution. The process flow of pre-decarbonization-copper-lead partial mixed flotation-copper-lead separation-tailings zinc and sulfur selection is adopted, and the method of concentration and fine grinding is used to achieve deep de-drug removal, effectively eliminating the influence of ore slime on flotation. At the same time, the high-efficiency collector A8 and the inhibitor T721 for copper-lead separation are used in the copper-lead partial mixed flotation operation to effectively realize the separation and recycling of copper, lead, zinc and sulfur, and significantly reduce the mutual content of concentrates.

[0003] However, in the actual beneficiation process of copper-lead-zinc ores, ball mills may be used in the flotation stage for different types of metals, but since the beneficiation production line of copper-lead-zinc ores is long, ball mills need to be moved back and forth between multiple flotation processes, or ball mills need to be added to multiple flotation processes, which is not conducive to the beneficiation operation of copper-lead-zinc ores and also increases the investment cost of flotation.

[0004] To this end, a flotation separation device for copper, lead and zinc ores is proposed, which has the advantages of easy ore re-grinding and improved flotation efficiency, thereby solving the problems in the above-mentioned background technology. Utility Model Content
