Problems solved by technology

[0002] Chalcopyrite is mainly copper-iron sulfide, which also contains trace amounts of gold, silver and other substances. It is the most widely distributed type of copper ore and the most important raw material for copper smelting. It is concentrated in Sichuan and Yunnan. There are relatively mature, stable and efficient technologies for extracting copper from ores, but there is still a lot of room for improvement in the existing technologies for the full extraction of copper from low-grade chalcopyrite ores

Abstract

The invention provides an improved type flotation agent. The improved type flotation agent is composed of butyl xanthate, ammonium dibutyl dithiophosphate, ethionine ester, erucic acid, maleic acid, polyethylene, alkylphenol polyglycol ether, ethyl alcohol, sodium dodecyl benzene sulfonate, coupling agent KH550 and water. The dispersion and collecting effects of the improved type flotation agent are quite good, the selectivity of the improved type flotation agent is good, and efficient flotation of copper in a low-grade chalcopyrite can be achieved.

Description

technical field [0001] The invention relates to the field of flotation agents, in particular to the field of chalcopyrite flotation agents. Background technique [0002] Chalcopyrite is mainly copper-iron sulfide, which also contains trace amounts of gold, silver and other substances. It is the most widely distributed type of copper ore and the most important raw material for copper smelting. It is concentrated in Sichuan and Yunnan. There are relatively mature, stable and efficient technologies for extracting copper from ores, but there is still a lot of room for improvement in the existing technologies regarding the full extraction of copper from low-grade chalcopyrite ores. Contents of the invention [0003] The purpose of the present invention is to propose an improved flotation agent with particularly good dispersion and collection effects and good selectivity, especially for low-grade chalcopyrite flotation. [0004] Technical scheme of the present invention is as f...
