Description
Technical field
The invention belongs to mineral floating collecting agent technical field, be specifically related to a kind of non-sulfide ore mineral floating collecting agent and its preparation method and application.
Background technology
Useful mineral, due to containing active carboxyl functional group, can separate with gangue by aliphatic acid and soap class effectively thereof, are the non-sulfide ore mineral floating collecting agents that a class is excellent.Because higher fatty acids is solid at normal temperatures, be insoluble in water, use inconvenience, therefore the saturated fatty acid of conventional oleic acid, linoleic acid, leukotrienes, ready denier oil acid and liquid, the most frequently used at present in industrial floatation process is oleic acid and modified product thereof and oxidized paraffin wax soap.Chinese patent (publication number is CN102600985A) discloses a kind of method of collecting agent for ilmenite, iron oxide ore flotation being mixed rear resaponifying by oleic acid, oxidized paraffin wax soap and aliphatic acid in proportion; Chinese patent (publication number is CN102921537A) discloses a kind of method of oleic acid flotation limonite; Chinese patent (publication number is CN101712014A) discloses a kind of method using alkaline oleic acid, neutral oleic acid and acid oleic acid segmentation flotation Multicategory-impurity single fluorite ore deposit respectively; Chinese patent (publication number is CN101585016A) discloses one oleic acid and makes collecting agent, with starch, sodium sulphate, hydrochloric acid, calgon as the inhibitor of barite mineral, to the method for low grade fluorite and barite FLOTATION SEPARATION; Chinese patent (publication number is CN103657860A) discloses the method for collecting agent floating and enriching zinc silicate mineral under acid condition of a kind of oxidized paraffin wax soap and dodecyl sodium sulfate interworking; Chinese patent (publication number is CN101648157A and CN101757983A) discloses that a kind of fatty acid mixed flotation with comprising oleic acid is black, the method for scheelite; Chinese patent (publication number is CN102302982A) discloses a kind of beneficiation method reclaiming scheelite from gneiss type ore; Chinese patent (publication number is CN102716811A) discloses a kind of method of cotton oil acid and rape oil acid mixed acid flotation water-soluble weathering phosphorite ore; Chinese patent (publication number is CN102962144A) discloses a kind of method that saponification degree is about the oleic acid flotation bauxite of 50%.
Oleic acid is subject to the welcome of mineral floating producer deeply because collecting ability is strong and the scope of application is wide as collecting agent, but in flotation, also there is obvious shortcoming, namely selective not high, freezing tolerance is poor and dispersiveness is bad etc.; Though and oxidized paraffin wax soap has low price as the substitute of oleic acid, flotation results affects the advantages such as little by slurry temperature, when also existing alone, flotation performance is not as oleic acid, poor selectivity and the shortcoming such as concentrate grade is low.For different deficiency of giving ore deposit character, climate characteristic and oleic acid, oxidized paraffin wax soap class collecting agent, development of new and efficiently collecting agent become one of focus of technique of preparing development.
Add in oleic acid, oxidized paraffin wax soap and use surfactant, improve the micella molecules align of aliphatic acid, not only can improve oleic acid or the dispersiveness of oxidized paraffin wax soap in ore pulp, reduce the consumption of collecting agent, and can flotation selectivity be improved, improve flotation speed, increase the coverage rate of mineral surfaces.Anion surfactant is divided into the large class of carboxylate, sulfuric acid, sulfonate and phosphate ester salt four, there is good decontamination, foaming, dispersion, emulsification and the characteristic such as wetting, anion surfactant is utilized to add enuatrol or oxidized paraffin wax soap collecting agent used in combination at present, performance has had and has promoted by a relatively large margin, patent and report more.But find in industrial practice, this kind of collecting agent is good due to frothing capacity, creates certain negative effect, reduce the selective floation of mineral floating to valuable mineral, be unfavorable for the separation of mineral mineral floating.
In order to search out suitable surfactant formula raw material, the present invention is according to mixed reagent, synergistic thinking, from single raw material to polytype raw material, float test is carried out in mixing, research finds, inside various alcohols, isooctanol has best defoaming effect, and the surfactant derived by isooctanol also has the effect of low foam.In isooctanol molecular formula, introduce the structure of phosphate, the surface tension of product can be improved, reduce the foam of product further, thus be conducive to the flotation of mineral.
Di-phosphorus pentonide documents and materials report is more, Di-phosphorus pentonide is a kind of new nonionic surfactant, comprise phosphoric acid-2-ethylhexyl and 2-ethylhexyl phosphoric acid-2-ethylhexyl two kinds of products, because of its have high, the resistance to hard water of solubility, acidproof, alkaline-resisting, high temperature resistant, emulsifying dispersivity is strong, wetability is good and the advantage such as easily biological-degradable, and be widely used in textile industry, it is mainly used for manufacturing bleeding agent and wetting agent.Have the investigation and application about Di-phosphorus pentonide, the field such as textile industry and rare metal extractant that is only limitted to shows good application prospect, and Di-phosphorus pentonide is gone back at present as the application of collecting agent in mineral floating, and there is not been reported.
Summary of the invention
Selective not high, the defect such as freezing tolerance is poor and dispersiveness is bad is all there is for oleic-acid in prior art and oxidized paraffin wax soap class flotation collector etc., find a kind of efficient surfactant being applicable to using in a variety of contexts, the defect fundamentally making up oleic-acid and oxidized paraffin wax soap class collecting agent is very important.One object of the present invention there are provided a kind of non-sulfide ore mineral floating collecting agent, phosphoric acid-2-ethylhexyl is added or/and after 2-ethylhexyl phosphoric acid-2-ethylhexyl at above-mentioned oleic-acid and oxidized paraffin wax soap class flotation collector, through fully mixing, participate in the micella molecules align of aliphatic acid, extremely be conducive to the dispersion of enuatrol ion in ore pulp, be increased in the coverage rate of mineral surfaces, substantially increase collecting performance, it has well selective and adsorptivity to non-sulfide ore, and it is water-soluble all better with dispersiveness, can use as mineral floating collecting agent.
Another object of the present invention there are provided a kind of preparation method of non-sulfide ore mineral floating collecting agent, and this preparation method's flow process is simple, and operation is easy to control, raw material sources are extensive, with low cost, safety and environmental protection, product recovery rate is higher and be easy to realize suitability for industrialized production.
