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

Embodiment 1

[0009] Mix 5 parts of dixanthate, 8 parts of butyl ammonium black medicine, 1 part of ethionate, 1 part of lauric acid, 1 part of myristic acid, 3 parts of tall oil, and 10 parts of alkylphenol polyethylene glycol ether, At 40°C, stir at a stirring frequency of 5000 rpm for 30 minutes, then add 5 parts of ethanol, 1 part of coupling agent KH550, and 30 parts of water. After heating to 45 °C, stir at a stirring frequency of 6000 rpm for 10 minutes , and finally add 1 part of sodium dodecylbenzenesulfonate, lower the temperature to 40° C., and stir at a stirring frequency of 5000 rpm for 10 minutes to obtain the improved mineral flotation agent.

Embodiment 2

[0011] Mix 7 parts of butyl xanthate, 10 parts of butyl ammonium black medicine, 3 parts of ethionate, 5 parts of lauric acid, 5 parts of myristic acid, 7 parts of tall oil, and 15 parts of alkylphenol polyethylene glycol ether, At 30°C, stir at a stirring frequency of 10,000 rpm for 20 minutes, then add 10 parts of ethanol, 3 parts of coupling agent KH550, and 50 parts of water, heat up to 35°C, and stir at a stirring frequency of 12,000 rpm for 20 minutes , and finally add 5 parts of sodium dodecylbenzenesulfonate, lower the temperature to 30° C., and stir at a stirring frequency of 5000 rpm for 20 minutes to obtain the improved mineral flotation agent.

Abstract

The invention provides an improved mineral flotation agent preparation method. The improved mineral flotation agent preparation method comprises the following steps of: mixing butyl xanthate, ammonium dibutyl dithiophosphate, ethionine ester, lauric acid, myristic acid, tall oil and alkylphenol polyglycol ether below 30-40 DEG C; stirring for 20-30 minutes at the stirring frequency of 5000-10000 revolutions per minute, afterwards adding ethyl alcohol, a coupling agent KH550 and water, and stirring for 10-20 minutes at the frequency of 6000-12000 revolutions per minute at the temperature of 35-45 DEG C; and finally adding sodium dodecyl benzene sulfonate, 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 mineral flotation agent preparation method is simple in operation. An obtained improved mineral flotation agent has good dispersion and collection effects and very good selectivity and is particularly capable of efficiently floating copper in low-grade copper chalcopyrite.

Description

technical field [0001] The invention relates to the field of mineral flotation agents, in particular to the field of brass 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 an improved mineral flotation agent with good dispersion and collection effects and particularly good selectivity, especially for low-grade chalcopyrite flotation. [0004] Technical scheme ...
