Abstract

The invention provides a preparation method of an improved flotation agent for copper ore selection. The preparation method of the improved flotation agent for copper ore selection comprises the steps of mixing lauric acid, palmitoleic acid, maleic anhydride, linseed oil 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 ore selection.

Description

A kind of preparation method of modified model copper mine concentration flotation agent

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 dispersion respond well with collecting, selectivity is particularly excellent, particular for copper The preparation method of the flotation agent that ore deposit is selected.

Technical scheme is as follows:

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

1) by Low Density Polyethylene mixing that lauric acid, palmitoleic acid, maleic anhydride, Semen Lini oil, molecular weight are 500 ~ 2000 After at 50 ~ 60 DEG C stir 10 ~ 20min, stirring frequency is 5000 ~ 10000 revs/min, 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, 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, water 30 ~ 50 Part.

Operating process of the present invention is simple, and the flotation agent dispersion of gained is respond well with collecting, and selectivity is particularly excellent, The copper in mixture can be chosen expeditiously.
