Description
Technical field
The invention belongs to mineral floating technical fields, and in particular to a kind of efficient combination collecting agent and preparation method thereof.
Background technique
Phosphorus ore is the important chemical industry raw mineral materials of a variety of phosphorus products such as preparing phosphoric acid, phosphate fertilizer, have irreplaceability, can not
Reproducibility.In the entire phosphorus ore reserves in China, mid-low grade collophanite ore accounts for 80%, is the main body of China's rock phosphate in powder, the phosphorus in ore
Lime stone majority exists in colloid, and mutually cementing with dolomite, clay mineral etc., and symbiosis is complicated, wherein being with silicate
Main dirt content highest, therefore to obtain and meet relieving haperacidity, the qualified phosphorus concentrate of system fertilizer requirement, using suitable beneficiation method
Silicate is rejected to be necessary.In phosphate rock floating desiliconization impurity removal process, direct flotation is relatively mature, but technique is relatively
Complexity, collecting agent is mostly based on anion fatty acid soaps, and type is more, foam is more and dosage is big, and final phosphorus concentrate is difficult to
Sedimentation, subsequent job is difficult, needs to heat flotation when environment temperature is lower, causes beneficiation cost higher.Although the country is just
It constantly brings forth new ideas in flotation collector and technical study, but most also because dosing is big, phosphorus loses big, not easy to control etc. lack
Point leads to the seldom of truly industrialized production.As CN 104907183A discloses a kind of silico-calcium matter low grade collophanite
Direct reverse flotation technique is positive flotation collector, using amphoteric collector as reverse flotation collecting with amide-containing fatty acid soaps collecting agent
Agent sweeps the closed circuit flow of middling recurrence using a positive and a negative, though the dosage of simple process, collecting agent and inhibitor compared with
Greatly, reagent cost is higher；CN 102179308A discloses a kind of ore dressing side for removing iron, aluminum sesquioxide in collophane
Method, direct reverse flotation collecting agent select normal fat acids, using isomery mixing-in fat amine and synergist mixed alcohol as sesquialter oxygen
Compound collecting agent takes off R through direct reverse flotation technique+reverse flotation2O3Joint process, for the sesquichloride of Yunnan Phosphate
Removing practical application has good effect, but does not relate to the practical application of other region silicon calcium collophanites, and universality is narrow, and
The pH regulator dosage that direct reverse flotation technical process uses is larger, and reagent cost is high.In addition newest disclosed direct flotation collecting agent
In patented technology, rarely has the practical application being related to anionic collector and cationic surfactant composite reagent.
Therefore, develop environment-friendly high-efficiency, dosing are low, resistance to hard water ability is strong, subsieve flotation when foaming properties it is good and easy
In the combined capturing and collecting agent that uses of regulation, it is more in line with the processing principle of the reagent combination factually exclusive customization of border mineral, is quick reality
The existing industrialized effective way of phosphate rock floating desiliconization dealuminzation and collophane take off silicate impurity key problem urgently to be resolved.
Summary of the invention
In view of the shortcomings of the prior art, it is an object of the present invention to provide one kind to be used for flotation removing silico-calcium matter glue phosphorus
The efficient combination collecting agent of sial impurity in mine, by weight, which includes:
70-80 parts of long chain fatty acids soaps, 10-25 parts of anionic foaming agents, 5-10 parts of non-ionic foam stabilisers, 2-7 parts
Cationic synergist.
Collector dosage provided by the invention is low, collecting ability is strong, selectivity is good, anti-argillization ability is strong, resistance to hard water, foam
Measure it is moderate, environmental protection it is cheap, be applicable to flotation at low temperature and efficient separation can be carried out under pH value 9-11 range.
In collecting agent of the present invention, due to the presence of anion foaming agent and nonionic foam stabiliser, can effectively it prevent
Frothing capacity is poor caused by only unsaturated double-bond exists in fatty acid soaps, with the weak defect of mine ability, that is, ensure that main body rouge
Fat acid soap has had both excellent collecting ability to the selectivity of phosphate mineral again.And the addition of cationic amine can significantly drop
Surface tension of the low anionic collector in ore pulp solution system widens target minreal and gangue mineral surface potential difference,
The synergistic function between fatty acid soaps and other surfaces activating agent can be strengthened.Make collecting agent that there is excellent water solubility, catch
Receive performance and stable surface-active.
Collecting agent of the present invention due to zwitterion neutralize and formed special molecular structure, have good anticalcium, magnesium from
The ability of son, i.e., good resistance to hard water ability, while surface nature is insensitive under pH value 9-11 range.
For conventional direct flotation anionic collector currently on the market, dosing of the invention is few, formula combination
Significant effect, reagent cost are greatly lowered, while being had and being used under cryogenic, the performance that resistance to hard water, anti-argillization ability are strong,
More importantly because low in cost and use condition is not harsh, there is preferable industrial applications prospect.
Preferably, the long chain fatty acids soap is enuatrol, linoleic acid sodium, any two kinds in linolenic acid sodium.More preferably
, by above-mentioned any two kinds of compositions formed, the mass ratio of two kinds of components is 1:1.
It should be pointed out that using above-mentioned unsaturated fatty acid soap combination of two, it is good excellent floating that selectivity may be implemented
Select index.
It is another object of the present invention to provide the methods for preparing above-mentioned collecting agent, and this method comprises the following steps:
1) by weight, 70-80 parts of long chain fatty acids soaps, 10-25 parts of anionic foaming agents, 5-10 parts of non-ionic foams
Stabilizer, 2-7 parts of cationic synergist, mixing；
2) weight, which is added, is in 19-49 times of gross weight of step 1) gains of water, water-bath be sufficiently stirred to get.
Preferably, long chain fatty acids soap described in step 1) are enuatrol, linoleic acid sodium, any two in linolenic acid sodium
Kind.It is furthermore preferred that the mass ratio of two kinds of components is 1:1 by above-mentioned any two kinds of compositions formed.
Preferably, temperature is 60-80 DEG C when water-bath in step 2, mixing time 30min.
It should be pointed out that when preparing collecting agent of the present invention, to bath temperature, mixing time without particular/special requirement, only
It needs each component being dissolved in water.Stirring 30min at 60-80 DEG C is taken to be intended merely to more convenient acquisition collecting agent of the invention
?.
It is another object of the present invention to provide application of the above-mentioned collecting agent on flotation removing sial impurity.For from
For Selective Separation silicate with for phosphate, the effect of collecting agent of the invention is more significant in silicon calcium collophanite.This hair
Bright collecting agent can use under conditions of 10 ~ 25 DEG C, and the rock phosphate in powder big suitable for clay content is caught in conjunction with matched floatation process
It receives agent dosage and is generally 1500-2500g/t raw ore, the effect that efficient selective excludes silicate impurity can be obtained.
Compared with traditional direct flotation collecting agent, beneficial effects of the present invention:
1) combined capturing and collecting agent raw material sources of the invention are extensive, economic and environment-friendly；
