Abstract

The invention provides a preparation method of an improved flotation agent for copper-molybdenum selection. The preparation method of the improved flotation agent for copper-molybdenum selection comprises the steps of mixing lauric acid, palmitoleic acid, maleic anhydride, linseed oil, acrylic acid and low density polyethylene with the molecular weight being 500 to 2,000, and then stirring for 10 to 20min at the temperature of 50 to 60 DEG C to obtain a first mixture, wherein the stirring frequency is 5,000 to 10,000 r/min; adding butyl xanthate, O-isopropyl N-ethyl thiocarbamate, tall oil, alkylphenol polyglycol ether, alcohol, a coupling agent KH550 and water into the first mixture, and stirring for 10 to 20min at the temperature of 35 to 45 DEG C with the frequency of 6,000 to 12,000 r/min to obtain a second mixture; adding sodium dodecyl benzene sulfonate into the second mixture, and stirring for 10 to 20min at the temperature of 30 to 40 DEG C with the frequency of 5,000 to 10,000 r/min. The prepared flotation agent is favorable in dispersion and collection effect, excellent in selectivity, and particularly suitable for copper-molybdenum selection.

Description

A kind of preparation method of the modified model selected flotation agent of copper molybdenum

Technical field

The present invention relates to flotation agent field, particularly to copper mine concentration flotation agent field.

Background technology

Copper mine is during extracting copper, when roughly selecting when generally including multi mineral mixing mixes with two to three kinds of mineral Selected, relative to roughly selecting the selective power to target minerals, selected requirement is higher, if selected effective, the most permissible After selected, directly carry out being concentrated to give high-quality concentrate, therefore improve selected ability to obtaining high-quality concentrate meaning weight Greatly.

Summary of the invention

It is an object of the invention to propose a kind of copper, molybdenum dispersion respond well with collecting, excellent selected with floating of selectivity Select the preparation method of agent.

Technical scheme is as follows:

The preparation method of a kind of modified model selected flotation agent of copper molybdenum, comprises the following steps:

1) it is the low density polyethylene of 500 ~ 2000 by lauric acid, palmitoleic acid, maleic anhydride, Semen Lini oil, acrylic acid, molecular weight Stirring 10 ~ 20min after alkene mixing at 50 ~ 60 DEG C, stirring frequency is 5000 ~ 10000 revs/min, and reaction obtains the first mixture；

2) by butyl xanthate, ethyl ammonia sulfate, tall oil, alkyl phenol polyglycol ether, ethanol, coupling agent KH550 adds first with water In mixture, under the temperature of 35 ~ 45 DEG C, the frequency of 6000 ~ 12000 revs/min, stir 10 ~ 20min, obtain the second mixture；

3) in the second mixture, dodecylbenzene sodium sulfonate is added, at the temperature of 30 ~ 40 DEG C, the frequency of 5000 ~ 10000 revs/min 10 ~ 20min is stirred under rate.

Preferably: by mass parts, described flotation agent includes butyl xanthate 10 ~ 20 parts, ethyl ammonia sulfate 1 ~ 5 part, lauric acid 1 ~ 5 Part, palmitoleic acid 1 ~ 5 part, maleic anhydride 5 ~ 7 parts, Semen Lini oil 7 ~ 10 parts, tall oil 3 ~ 7 parts, 3 ~ 5 parts of acrylic acid, polyethylene 5 ~ 10 parts, alkyl phenol polyglycol ether 10 ~ 15 parts, ethanol 5 ~ 10 parts, dodecylbenzene sodium sulfonate 1 ~ 5 part, coupling agent KH5501 ~ 3 Part, 30 ~ 50 parts of water.

Operating process of the present invention is simple, and the flotation agent of gained is good to the dispersion effect of copper, molybdenum, and the collecting to copper is imitated Fruit is good, and selectivity is particularly excellent, it is possible to the copper in the most selected copper molybdenum mixture.
