Problems solved by technology

[0003] Flotation agents such as xanthate, thiophosphate and mercaptan, thiaminate, xanthate, black drug ester, xanthate, etc. are the dominant collectors in the existing lead-zinc oxide flotation process , but in the actual beneficiation, most of the results cannot meet the design requirements, and the recovery rate of lead-zinc concentrate is low, resulting in a waste of mineral resources

Abstract

The invention discloses a beneficiation reagent for flotation of lead and zinc from lead-zinc oxide ore and a preparation method thereof. The beneficiation reagent is prepared from the following raw materials in parts by weight: 15-25 parts of diesel oil, 10-20 parts of sodium carbonate, 20-30 parts of sodium sulfide, 40-50 parts of 3, 3-dimethylbutyric acid, 13-18 parts of sulfur, 15-30 parts ofesterified xanthate, 25-45 parts of 3-amino-2 butenoic acid, 4-5 parts of quick lime and 20-24 parts of an activating agent. The beneficiation reagent has the characteristics of high separation efficiency, high yield, low consumption, simple and reliable process flow, easiness in operation and the like, is suitable for beneficiation application of the re-vulcanized and oxidized mixed lead-zinc ore, and can bring good economic benefits to the lead-zinc ore.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to a mineral processing agent for flotation of lead-zinc oxide ore and a preparation method thereof. Background technique [0002] At present, the mineral raw materials for dressing and smelting lead-zinc in my country are mainly lead-zinc sulfide, lead-zinc oxide, sulfurized and oxidized mixed lead-zinc, etc. According to the technical conditions of dressing and smelting, the lead-zinc ore is divided into three natural types according to the ratio of lead-zinc oxide and lead-zinc sulfide. That is, sulfide ore, containing less than 10% lead and zinc oxide; oxidized ore, containing more than 30% lead and zinc oxide; mixed ore, containing 10% to 30% lead and zinc oxide. [0003] Flotation agents such as xanthate, thiophosphate and mercaptan, thiaminate, xanthate, black drug ester, xanthate, etc. are the dominant collectors in the existing lead-zinc oxide flotation process ...
