Abstract
The present invention proposes a kind of preparation method of low-grade chalcopyrite flotation agent, it comprises following process: at 50 ~ 60 DEG C, stir 10 ~ 20min after erucic acid, maleic acid being mixed with low density polyethylene (LDPE), stirring frequency is 5000 ~ 10000 revs/min, obtains the first mixture; By butyl ammonium aerofloat, tall oil, ethylene glycol ethyl ether, ethanol, coupling agent KH550 and water add in the first mixture, stir 10 ~ 20min, obtain the second mixture under the temperature of 35 ~ 45 DEG C, the frequency of 6000 ~ 12000 revs/min; In the second mixture, add neopelex, under the temperature of 30 ~ 40 DEG C, the frequency of 5000 ~ 10000 revs/min, stir 10 ~ 20min.The method is simple, and dispersion and the collecting of gained low-grade chalcopyrite flotation agent are respond well, well selective, can floatingly select the copper in low-grade chalcopyrite efficiently.
Description
Technical field
The present invention relates to flotation agent field, particularly chalcopyrite flotation agent field.
Background technology
Chalcopyrite is mainly copper iron sulfide, wherein also containing materials such as micro-gold, silver, it is the copper mine type distributing the widest, also be the topmost raw material of copper metallurgy, concentrated distribution is had at Sichuan and Yunnan area, to existing more ripe, stable, the efficient technology of the extraction of copper in general chalcopyrite, but still there is larger room for improvement about the abundant extraction of copper in low-grade chalcopyrite in prior art.
Summary of the invention
The object of the invention is to propose a kind of dispersion respond well, well selective with collecting, especially for the preparation method of the flotation agent of low-grade chalcopyrite flotation.
Technical scheme of the present invention is as follows:
A preparation method for low-grade chalcopyrite flotation agent, comprises the following steps:
1) at 50 ~ 60 DEG C, stir 10 ~ 20min after the low density polyethylene (LDPE) being 500 ~ 2000 by erucic acid, maleic acid and molecular weight mixes, stirring frequency is 5000 ~ 10000 revs/min, obtains the first mixture;
2) by butyl ammonium aerofloat, tall oil, ethylene glycol ethyl ether, ethanol, coupling agent KH550 and water add in the first mixture, stir 10 ~ 20min, obtain the second mixture under the temperature of 35 ~ 45 DEG C, the frequency of 6000 ~ 12000 revs/min;
3) in the second mixture, add neopelex, under the temperature of 30 ~ 40 DEG C, the frequency of 5000 ~ 10000 revs/min, stir 10 ~ 20min.
Preferably: by mass parts, described flotation agent comprises butyl ammonium aerofloat 10 ~ 20 parts, erucic acid 1 ~ 5 part, maleic acid 1 ~ 5 part, polyethylene 2 ~ 10 parts, tall oil 3 ~ 7 parts, ethylene glycol ethyl ether 10 ~ 15 parts, ethanol 5 ~ 10 parts, neopelex 1 ~ 5 part, coupling agent KH5501 ~ 3 part, 30 ~ 50 parts, water.
Operating process of the present invention is simple, and the flotation agent dispersion prepared is respond well, well selective with collecting, can floatingly select the copper in low-grade chalcopyrite efficiently.
