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 chalcopyrite flotation agent preparation method. The improved chalcopyrite flotation agent preparation method comprises the following steps of: firstly mixing erucic acid, maleic acid and low density polyethylene with the molecular weight of 500-2000, and afterwards stirring for 10-20 minutes at the frequency of 5000-10000 revolutions per minute at the temperature of 50-60 DEG C to obtain a first mixture; then adding butyl xanthate, ethionine ester, alkylphenol polyglycol ether, ethyl alcohol, a coupling agent KH550 and water to the first mixture, and stirring for 10-20 minutes at the frequency of 6000-12000 revolutions per minute at the temperature of 35-45 DEG C to obtain a second mixture; and finally, adding sodium dodecyl benzene sulfonate to the second mixture, and stirring for 10-20 minutes at the frequency of 5000-10000 revolutions per minute at the temperature of 30-40 DEG C. The improved chalcopyrite flotation agent preparation method is simple in operation. An obtained chalcopyrite flotation agent has good dispersion and collection effects and very good selectivity and is particularly capable of efficiently floating copper in low-grade chalcopyrite.

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 a method for preparing a flotation agent with good dispersion and collection effects and particularly good selectivity, especially for low-grade chalcopyrite flotation. [0004] Technical scheme of the present inve...
