Thing, bauxite concentrate is produced, improve the alumina silica ratio of bauxite resource, then with advanced, economic alumina producing Bayer process.Aluminium
Native ore deposit ore dressing uses direct-flotation desiliconisation technique, and collecting agent is mainly anionic surfactant, and conventional medicament includes：Oil
Acid, tall oil, neutral oil, neopelex, lauryl sodium sulfate, oxidized paraffin wax soap, 731,733, styrene phosphorus
Acid etc., has that collecting agent low temperature adaptability is poor, flotation selectivity is poor, aluminium mineral and siliceous mineral separation are tired in actual production process
The problems such as difficult, concentrate grade and the rate of recovery are difficult to ensure that.
Patent of invention [CN 101983777B] discloses " a kind of alumyte flotation compound collecting agent ", and the collecting agent is by work
The mono carboxylic aliphatic acid of industry grade, alkyl hydroximic acid and alkylol composition, by mass percentage for：5%~15% mono carboxylic fat
Acid, 20%~55% alkyl hydroximic acid and 30%~65% alkylol；Although the invention strengthens collecting agent by introducing hydroximic acid
Selective collecting ability, alkylol is introduced into improve the intersolubility of each component in compound, still, this composite collector is in ore deposit
Dispersion effect in slurry is bad；The stability of compound system is poor, short to the action time of mineral, and collecting ability improves limited.
The content of the invention
In view of the above-mentioned problems, the technical problem to be solved in the present invention is：A kind of direct flotation collecting agent of bauxite is provided, both
Can overcome poor selectivity existing for traditional oleic-acid collecting agent, it is weak to the collecting ability of subparticle the shortcomings of, and can improves
The dispersion effect and stability of collecting agent, the dosage of foaming agent is reduced while collecting ability is improved.
The present invention uses following technical scheme：The present invention provides a kind of direct flotation collecting agent of bauxite, the collecting agent by
Emulsifying agent, oleic-acid collecting agent, octyl group hydroximic acid collecting agent, kerosene and water form through ultrasonic emulsification, and its quality proportioning is：Breast
Agent：Oleic-acid collecting agent：Octyl group hydroximic acid collecting agent：Kerosene：Water is 1:2~5：10~15：10~15：64 ~ 77, ultrasonic wave hair
Radio frequency rate is 25 ~ 30kHz, and the ultrasonic emulsification time is 30 ~ 60min.
Described oleic-acid collecting agent is oleic acid, enuatrol and linoleic one kind.
The chemical molecular structural formula of described octyl group hydroximic acid collecting agent is CH3CH2CH2CH2CH2CH2CH2CONHOH。
Described emulsifying agent is one kind in Tween-20, PEG-400.
The applicable domestic and international bauxite of the present invention, particularly diaspore type bauxite of the alumina silica ratio in 3.3-3.4.
Compared with prior art, the present invention has the following advantages：The collecting agent stability is good, at room temperature can be with emulsion shape
Formula is stabilized 60min, adds emulsion drop d after water50Being basically unchanged, can stably it be played a role within the flotation of ore pulp time；
The dispersibility of ore pulp is strong, abundant with mineral effect, and it is obvious to improve floatation indicators；Foaming characteristic is good, and foam is tiny, uniform, can subtract
Few foaming agent uses, or without foaming agent；Collecting agent, frother dosages are reduced, and reduce reagent cost.
