Abstract
The invention provides a preparing method for a flotation agent. Erucic acid, maleic acid and low density polyethylene are firstly mixed to be stirred at the temperature ranging from 50 DEG C to 60 DEG C for 10 min to 20 min, the stirring frequency ranges from 5000 turn/min to 10000 turn/min, and a first mixture is obtained; then butyl xanthate, ammonium dibutyl dithiophosphate, glycol ether, ethanol, a coupling agent KH550 and water are added into the first mixture to be stirred at the temperature ranging from 35 DEG C to 45 DEG C for 10 min to 20 min under the frequency ranging from 6000 turn/min to 12000 turn/min, and a second mixture is obtained; and finally, sodium dodecyl benzene sulfonate is added into the second mixture to be stirred at the temperature ranging from 30 DEG C to 40 DEG C for 10 min to 20 min under the frequency ranging from 5000 turn/min to 10000 turn/min. The preparing method is easy to operate, and the obtained flotation agent is good in dispersing and collecting effect, good in selectivity, and particularly capable of efficiently floating out copper in low-grade chalcopyrite.
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 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 xanthate, butyl ammonium aerofloat, 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 xanthate 8 ~ 10 parts, butyl ammonium aerofloat 8 ~ 10 parts, erucic acid 1 ~ 5 part, maleic acid 1 ~ 5 part, low density polyethylene (LDPE) 2 ~ 10 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.
