Description
Technical field
The invention belongs to mineral floating collecting agent technical field, and in particular to a kind of non-sulfide ore mineral floating collecting agent and
Its preparation method and application.
Background technology
Aliphatic acid and its soaps are due to that containing active carboxyl functional group, effectively can divide useful mineral and gangue
Open, be a kind of excellent non-sulfide ore mineral floating collecting agent.Because higher fatty acids is solid at normal temperatures, water is insoluble in,
In-convenience in use therefore conventional oleic acid, linoleic acid, leukotrienes, the saturated fatty acid of ready denier oil acid and liquid, in industrial flotation
Oleic acid and its modified product and oxidized paraffin wax soap are most commonly used that in technique at present.Chinese patent（Publication No.

Oleic acid is welcome by mineral floating producer deeply as collecting agent because collecting ability is strong and use range is wide, but
Also the shortcomings that obvious in flotation be present, i.e., the not high, freezing tolerance of selectivity is poor and poor dispersion etc.；And oxidized paraffin wax soap conduct
Though the substitute of oleic acid have it is cheap, flotation results are influenceed the advantages that small by slurry temperature, there is also it is alone when flotation
Performance is not so good as oleic acid, the shortcomings such as poor selectivity and concentrate grade are low.For it is different to ore deposit property, climate characteristic and oleic acid,
The deficiency of oxidized paraffin wax soaps collecting agent, development of new and efficient collecting agent turn into one of focus of technique of preparing development.
Addition uses surfactant in oleic acid, oxidized paraffin wax soap, improves the micella molecules align of aliphatic acid, not only may be used
To improve the dispersiveness of oleic acid or oxidized paraffin wax soap in ore pulp, the consumption of collecting agent is reduced, and flotation selection can be improved
Property, flotation speed is improved, increases the coverage rate of mineral surfaces.Anion surfactant is divided into carboxylate, sulfuric acid, sulfonic acid
Salt and the major class of phosphate ester salt four, there is the characteristics such as preferable decontamination, foaming, scattered, emulsification and wetting, currently with anion table
Face activating agent is added to the collecting agent that enuatrol or oxidized paraffin wax soap are used in mixed way, and performance has to be lifted by a relatively large margin, patent and
Report more.But found in industrial practice, this kind of collecting agent generates one because frothing capacity is good to mineral floating
Fixed negative effect, selective floation of the mineral floating to valuable mineral is reduced, is unfavorable for the separation of mineral.
In order to search out suitable surfactant formula raw material, the present invention according to mixed reagent, the thinking of synergy,
From single raw material to polytype raw material, mixing carries out float test, and research is found, inside various alcohols, isooctanol has most
Good defoaming effect, surfactant also has the effect of low foam as derived from isooctanol.Introduced in isooctanol molecular formula
The structure of phosphate, the surface tension of product can be improved, the foam of product further be reduced, so as to be advantageous to the flotation of mineral.
Di-phosphorus pentonide documents and materials report is more, and Di-phosphorus pentonide is a kind of new nonionic surfactant,
Including phosphoric acid -2- ethylhexyls and 2- ethylhexyl phosphoric acid -2- two kinds of products of ethylhexyl, because it has solubility high, resistance to
Hard water, acidproof, alkaline-resisting, high temperature resistant, emulsifying dispersivity are strong, wetability is good and the advantages that easily biological-degradable, and in textile industry
It is widely used, it is mainly used for manufacturing bleeding agent and wetting agent.The research and application of Di-phosphorus pentonide are related to, is only limitted to
The field such as textile industry and rare metal extractant shows good application prospect, and Di-phosphorus pentonide is in mineral floating
Application as collecting agent not yet appears in the newspapers at present.
The content of the invention
Not high, the freeze proof energy of selectivity for oleic-acid in the prior art and oxidized paraffin wax soaps flotation collector etc. all be present
The defects of power difference and poor dispersion, a kind of efficient surfactant for being adapted to use in a variety of contexts is found, fundamentally
The defects of making up oleic-acid and oxidized paraffin wax soaps collecting agent is particularly important.It is an object of the present invention to provide a kind of non-
Sulphide ore mineral floating collecting agent, phosphoric acid -2- ethyl hexyls are added in above-mentioned oleic-acid and oxidized paraffin wax soaps flotation collector
After base ester or/and 2- ethylhexyl phosphoric acid -2- ethylhexyls, through fully mixing, the micella molecules align of aliphatic acid is participated in, ten
It is scattered in ore pulp point to be advantageous to oleic acid sodium ion, increases the coverage rate in mineral surfaces, substantially increases collecting performance, its
There is good selectivity and adsorptivity to non-sulfide ore, and water-soluble and dispersiveness is preferable, can be caught as mineral floating
Agent is received to use.
It is another object of the present invention to provide a kind of preparation method of non-sulfide ore mineral floating collecting agent, the system
