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 a preparation method for an improved low-grade chalcopyrite flotation agent. The preparation method comprises the following steps that erucic acid, maleic acid and low-density polyethylene with the molecular weight of 500-2,000 are mixed and then stirred at the temperature of 50 DEG C to 60 DEG C for 10 min to 20 min, the stirring frequency ranges from 5,000 rpm to 10,000 rpm, and a first mixture is obtained; ammonium dibutyl dithiophosphate, ethionine ester, tall oil, alkylphenol polyglycol ether, ethanol, a coupling agent KH550 and water are added to the first mixture and are stirred at the temperature of 35 DEG C to 45 DEG C at the frequency of 6,000 rpm to 12,000 rpm for 10 minutes to 20 minutes, and a second mixture is obtained; and sodium dodecylbenzene sulfonate is added to the second mixture and is stirred at the temperature of 30 DEG C to 40 DEG C at the frequency of 5,000 to 10,000 rpm for 10 minutes to 20 minutes. The method is easy to implement, the dispersing and collecting effects of the improved low-grade chalcopyrite flotation agent are good, the selectivity is good, and copper in low-grade chalcopyrite can be obtained in a flotation manner efficiently.
