Description
Technical field
The invention belongs to collophane reverse flotation technical field, more particularly to a kind of Collophane anti-floatation collector and its preparation
Method.
Background technology
Phosphorus ore is important industrial chemicals, is widely used in agricultural, medicine, military affairs, food energy industry.Although China's phosphorus ore storage
Amount is larger, but with Morocco, the U.S. can compared with, China's rock phosphate in powder grade is relatively low and flotability can be relatively poor.Additionally, China
The many rich ores of lean ore are few, and rock phosphate in powder has to pass through the production requirement that phosphoric acid by wet process could be met after beneficiation enrichment.
Generally speaking phosphorus ore is divided into carbonate-type, silicate-type and mixed type, carbonate-type in the form of its stone-like pulse is present
Collophane, its stone-like pulse mainly exists with the form of dolomite, calcite.It is by anti-floating to exclude dolomite, the method for calcite
Choosing, its technology characteristics meet the principle of " floating few suppression is more ", and energy consumption is relatively low, is the prevailing technology of currently processed carbonate-type phosphorus ore.
Collecting agent in reverse floatation mainly utilizes fatty acid prepared by Oleum Brassicae campestriss, soybean oil based on vegetable fatty acids, such as.These plants
Oil price lattice are higher, do not only exist the problem that grain is striven with people, and because synergist selects improper, cause that low-temperature solubility is poor, disperse
Ability is low, causes its consumption to remain high.Additionally, the Ca in ore pulp2+、Mg2+Unavoidable ion can consume fatty-acid collector, make
It is further up into collector dosage.
The Chinese patent application of Application No. CN201310029412.3 discloses one kind to turn waste into wealth waste oil and carries out
The method for preparing collophane reverse flotation carbonate mineral collecting agent.It is made up of waste oil, alkali and water, by its mass parts trench is compared
Oil：Alkali：Water=1：0.15～0.3：400 ratio mixing, reacts 1～1.5 hour under 40～80 DEG C of constant temperature, that is, make
Collophane reverse flotation carbonate mineral collecting agent is obtained, its step is：A. waste oil is heated to into 40～80 DEG C, filters, precipitates and remove
Solid waste is gone, then is dehydrated to waste oil moisture content less than 1%；B. waste oil composition is detected, according to testing result, is adjusted
Site preparation ditch line of oils part, the content for making C12～C18 in waste oil component reaches required index；C. waste oil is pressed：Alkali：Water=1：
0.15～0.3：400 ratio mixing, in 40～80 DEG C of constant temperature saponification 1～1.5 hour, adjusts pH value to 11, that is, obtain
Obtain collophane reverse flotation carbonate mineral collecting agent.Because waste oil source is complicated, different batches material component is changed greatly, must
Single fat acid (or purity higher fatty acid) must be added according to index, not only increased technological process, and be improve into
This.
The Chinese patent application of Application No. CN201410622082.3 discloses a kind of phosphate reverse flotation collecting agent, and this is caught
Receive agent to be made up of the component of following mass percent：Aliphatic acid polyethenoxy base ester salt 40～80%, alkyl polyoxyethylene base
Ether phosphoric acid monoester salt 14～50%, aliphatic alcohol polyethenoxy base ether 5～20%, Arlacel-20 1～10%.The collecting agent is applied to
Phosphate reverse flotation calcite.Although collecting agent is compared with fatty acid collecting agent, with very strong collecting ability and high selectivity；
Compared with the collecting agent of α-amido aryl phosphoric acids class, cheap, consumption is little, draws materials conveniently.But, due to the collecting agent with
Nonionic surfactant is raw material, and these raw materials have to pass through chemical industry synthesis and just can obtain, and its unit price is significantly larger than originated
The fatty acid collecting agent of nature, not with wide variety of prospect.
The content of the invention
The present invention is directed to the deficiencies in the prior art, there is provided a kind of Collophane anti-floatation collector and preparation method thereof.This
It is bright to be matched somebody with somebody by cationic surfactant, chelating agen and fatty acid complex, dispersive property of the fatty acid in phosphate ore pulp is improved, so as to have
Effect improves its collecting performance, eliminates Ca in ore pulp2+、Mg2+Deng the impact of unavoidable ion.
Technical scheme is as follows：A kind of Collophane anti-floatation collector, the collecting agent is by following weight portion
Raw material is made：Technical grade animal oil fatty acid 30-40 parts, inorganic base 5-10 parts, empgen BB 3-5 parts, fatty amine 1-3
Part, tween 2-4 parts, fatty alcohol-polyoxyethylene ether 3-5 parts, foaming agent 1-3 parts and water 33-55 parts.
One or more of the inorganic base in sodium carbonate, sodium hydroxide and sodium bicarbonate.
The one kind or several of the fatty amine in lauryl amine, octadecylamine and N, N- dimethyl dodecylamine
Kind.
One or more of the tween in tween 20, Tween-40, Tween-60 and tween 80.
The fatty alcohol-polyoxyethylene ether (AEO) is selected from fatty alcohol-polyoxyethylene ether -10, fatty alcohol-polyoxyethylene ether -15
With one or more in fatty alcohol-polyoxyethylene ether -20.
The foaming agent is selected from cocoanut fatty acid diethanolamide (6501), dodecylbenzene sodium sulfonate and dodecyl
One or more in sodium sulfate.
Collecting agent operation principle of the present invention is as follows：The present invention is simultaneously matched somebody with somebody by cationic surfactant with fatty acid complex, is subtracted
The intermolecular repulsive force that few fatty acid molecule is produced when mineral surfaces adsorb, so as to improve adsorbance, reaches raising fatty acid
The purpose of collecting ability；The empgen BB that the present invention is used has stronger resistance to hard water, can be with Ca in ore pulp2+、
Mg2+Hardly possible forms coordination compound except (exempting from) ion, reduces its consumption to collecting agent, and tween and fatty alcohol-polyoxyethylene ether can be effectively
Separate animals fatty acid oil, improves dispersive property of the fatty acid in phosphate ore pulp.Mutual synergism between each component promotes described
Collophane anti-floatation collector is better than conventional collecting agent, with wider range of application.
The present invention also provides the preparation method of the Collophane anti-floatation collector, and methods described operation is as follows：By industry
Level animal oil fatty acid, inorganic base and water are put in proportion in reactor, and stirring reaction completes saponification, according still further to ratio
Input empgen BB, fatty amine, tween, fatty alcohol-polyoxyethylene ether and foaming agent, continue to stir, and mix homogeneously is obtained
Collecting agent.
Saponification temperature is 70-90 DEG C in the preparation method, and the response time is 1-3 hours.
The collecting agent usage amount is 0.25～0.35kg/t raw ores, i.e., in pulp tank, by ore pulp and of the present invention
Collecting agent is mixed in proportion 3min, and being subsequently sent to flotation device carries out flotation.
Compared with prior art, the invention has the advantages that：The collecting agent that the present invention is provided has dispersive property
Well, the advantages of low operating temperature, efficiency high, compared with conventional collophane reverse flotation de-magging collector, collector dosage can decline
10% or so.The present invention solves technical grade for a long time with wide material sources, cheap technical grade animal oil as raw material
The hidden danger of animal oil backflow dining table.
