Abstract
The invention discloses composite collecting agent and application thereof, and belongs to the technical field of flotation separation. The collecting agent is obtained by mixing and saponification of mixed fatty acid, lower alcohol, polyglycerol ester, an alkylamine compound and inorganic base. The mixed fatty acid, the lower alcohol, the polyglycerol ester, the alkylamine compound and the inorganic base respectively account for, by mass, 65%, 12%, 2%, 1% and 20% of the mixed raw material. Through solubilizing effect generated by screening and compounding of various organics and saponification of the inorganic base to the fatty acid, water solubility of the fatty-acid collecting agent and dispersivity of the collecting agent in ore pulp are strengthened, so that effect of the collecting agent is improved, and good collecting capability of the collecting agent can be still kept under low temperature conditions; the collecting agent is suitable for being used at the ore pulp temperature of above 10 DEG C , and the quantity for use ranges from 800g/t to 1600g/t according to change of the content of bauxite in ore.
Description
Technical field
The present invention relates to a kind of composite collector and application, belong to floatation separating technology field.
Background technology
Al and Alalloy be current applications very widely, one of most economical applicable material.Bauxite is the optimum feed stock of producing metallic aluminium, and be also topmost application, its consumption accounts for more than 90% of world's bauxite total output.China's bauxite resource major part is the diaspore type bauxite of middle-low grade, enrichment is carried out by low cost, low energy consumption and oligosaprobic technique of preparing, obtaining high-grade bauxite product, and then carry out bayer process and produce aluminium, is the domestic technology path generally adopted at present.
At present, the flotation of bauxite has direct flotation and reverse flotation two kinds of techniques.Wherein, direct flotation mainly adds aliphatic acid or collecting agent direct flotation bauxite made by its soap salt, reverse flotation then uses cation-collecting agent flotation silicates gangue mineral, in current production practices, reverse flotation is received environmental impact factor and is still in experimental stage too much, the production of bauxite is still based on direct floatation process, its collecting agent mainly used has oleic acid, oxidized paraffin wax soap, naphthenic soap, tall oil, hydroximic acid etc., most popular is fatty acid collecting agent, in addition, neutral oil Chang Zuowei supplementary catching agent is mixed with fatty acid collecting agent.Fatty acid collecting agent due to the ionic mark of chemical bond formed with mineral surfaces Action of Metal Ions higher, so need the nonpolar hydrocarbon chain (general 8 ~ 18 carbon atoms) that coupling is longer, just can have suitable collecting ability, therefore the general fusing point of aliphatic acid as collecting agent is higher, in water, solubility is low, thus (particularly under cryogenic conditions) is dispersed poor in aqueous, cause reagent consumption larger, when being used alone or collecting ability strong, or foamability is not strong.Use this kind of collecting agent General Requirements slurry temperature to reach more than 20 DEG C, when low temperature uses, dosing sharply rises, and separating effect also obviously declines.Reclaiming problem for effectively solving bauxite flotation under cryogenic, the invention provides a kind of composite collector of flotation at low temperature bauxite.
Summary of the invention
The present invention is directed to the problem of collecting ability existing for fatty acid collecting agent and low temperature adaptability difference, a kind of NEW TYPE OF COMPOSITE collecting agent being suitable for selective floation bauxite under cryogenic conditions is provided, this collecting agent is by fatty acid mixed, lower alcohol, polyglycerol ester, there is saponification after alkylamide compound and inorganic base mix and obtain, in raw material upon mixing, the mass percent of fatty acid mixed is 65%, the mass percent of lower alcohol is 12%, the mass percent of polyglycerol ester is 2%, the mass percent of alkylamide compound is 1%, the mass percent of inorganic base is 20%.
Fatty acid mixed of the present invention has-COOH polar group, and non-polar group carbon containing number is 6 ~ 20, and non-polar group is containing 5% ~ 15% cycloalkanes.
Lower alcohol of the present invention is methyl alcohol or ethanol.
Polyglycerol ester of the present invention is polyhydroxy non-ionic surface active agent, to improve the water-soluble and dispersed of medicament.
Alkylamide compound of the present invention has-NH
2polar group, non-polar group carbon containing number is 3 ~ 6.
Inorganic base of the present invention is sodium carbonate or NaOH, realizes the saponification to fatty acid mixed.
Use under the slurry temperature of collecting agent of the present invention more than 10 DEG C, according to the change of minerals in bauxite content in ore, its consumption is between 800 ~ 1600g/t.
Feature of the present invention is: by the solubilising effect of the composite generation of the screening of gas chromatography and inorganic base to the saponification of aliphatic acid, enhance the water-soluble of fatty-acid collector and the dispersivity in ore pulp, thus improve the action effect of collecting agent, make collecting agent still keep good collecting performance under cryogenic.
Advantage relative to prior art:
(1) medicament involved in the present invention has strong selective collecting effect to bauxite;
(2) conventional bauxite collecting agent requires that slurry temperature reaches more than 20 DEG C, when low temperature uses, its dosing sharply rises, and separating effect also obviously declines, and collecting agent of the present invention is when slurry temperature is low to moderate about 10 DEG C, still have good separating effect to bauxite flotation, low temperature adaptability is strong.
