Abstract
The invention discloses a preparation method for a carbonic mud barite flotation collector. The raw materials of the carbonic mud barite flotation collector comprise, by weight, 70-80% of oleic acid, 15-20% of a surface active agent and 5-10% of a modifying agent. The preparation method comprises the steps that the oleic acid is added into a container at first, then the surface active agent and the modifying agent are matched to be a 5-10% water solution to be slowly added into the container, and adding and stirring are conducted at the same time; the water solution is mechanically activated for 2-3h at the normal temperature, after mechanical activation, the water solution is intensively dispersed through ultrasonic waves for 1-2h, and then a mixed solution, namely the target collector is obtained. The preparation method is simple and reliable, and easy to operate. Compared with a common barite collector, the carbonic mud barite flotation collector prepared based on the preparation method has the advantages of being high in dispersity and selectivity, the dosage of reagents is reduced by 1/4-1/3 in the using process, the good barite quality and recovery rate are obtained, and the preparation method is particularly suitable for grading carbonic mud barites.
Description
One, technical field
The present invention relates to the preparation method of ore floatation collecting agent, particularly a kind of carbon containing is containing the preparation method of mud floatation ion collector of heavy spar.
Two, background technology
At present, the widely used collecting agent of flotation barite has oxidized paraffin wax soap, enuatrol, oleic acid, alkyl sulfate, alkylsulfonate, amine etc. both at home and abroad.More to flotation barite collecting agent research both at home and abroad, relevant paper has the research of the separated middle hybrid collector of Barite flotation " fluorite with " of " the synthetic and Experimental study on ore dressing of A-22 ", the Mao Jufan of H.B. plug livre Lip river baby's " the bar new collector of flotation ", He Fayu etc. etc. etc.; Patents has Chinese patent application CN201110122581.2 to announce a kind of beneficiation collecting agent and preparation method thereof, Chinese patent application CN201210085130.0 has announced a kind of beneficiation collecting agent and using method thereof, and Chinese patent application CN200310106582.3 has announced a kind of preparation method of floatation ion collector of heavy spar.But the research for carbon containing containing mud floatation ion collector of heavy spar, has not yet to see relevant report.Adopt above-mentioned collecting agent to reclaim carbon containing and containing mud barite, cause that dosing is large, production cost is high.Therefore, research is prepared a kind of carbon containing and is seemed particularly urgent containing mud floatation ion collector of heavy spar.
Three, summary of the invention
The object of the present invention is to provide a kind of carbon containing containing the preparation method of mud floatation ion collector of heavy spar, the barite collecting agent of preparation can effectively weaken the adverse effect of Carbonaceous matter, sludge, and dosing is effectively reduced, and sorting index is good.
The present invention seeks to realize like this, a kind of carbon containing is containing the preparation method of mud floatation ion collector of heavy spar, by following raw materials by weight, formed: oleic acid 70~80%, surfactant 15~20%, adjusting agent 5~10%, first oleic acid is joined in container, surfactant, adjusting agent are made into 5~10% aqueous solution again and slowly add in container, limit edged stirs; Mechanical activation 2~3h under normal temperature condition, after mechanical activation, utilizes intensified by ultrasonic wave to disperse 1~2h again, and gained mixed liquor is target collecting agent.
Described surfactant is at least one in enuatrol, lauryl sodium sulfate, dodecyl sodium sulfate, and adjusting agent is at least one in NaOH, sodium carbonate, lime.
Outstanding advantages of the present invention is:
1, oleic acid is carried out after mechanical activation, utilize intensified by ultrasonic wave to disperse, generate the new collector with polymolecularity, high selectivity.
2, improved the dispersive property of collecting agent, evaded the large problem of conventional barite collecting agent dressing reagent consumption, made collector dosage fall few 1/4~1/3.
3, the collecting agent of preparation is selectively good, while sorting carbon containing containing mud barite, can obtain good barite grade and the rate of recovery.
Four, the specific embodiment
By specific embodiment, technical scheme of the present invention is described further below.

(1) lauryl sodium sulfate is made into 10% aqueous solution, sodium carbonate is made into 10% aqueous solution;
(2) oleic acid is poured in container, slowly added lauryl sodium sulfate aqueous solution, aqueous sodium carbonate, limit edged stirs, then under normal temperature condition mechanical activation 3h;
(3) by after above-mentioned mixed liquor mechanical activation 3h, utilize intensified by ultrasonic wave to disperse 1h, gained mixed liquor is finished product collecting agent.
Embodiment 3
The present embodiment is that the collecting agent of preparation described in embodiment 1, embodiment 2 sorts with conventional barite collecting agent oxidized paraffin wax soap, oleic acid, enuatrol, lauryl sodium sulfate the comparative test result that carbon containing contains mud barite ore, in Table 1.Adopt one slightly to sweep four Seiko process flow flotation barites.Barite raw ore barium sulfate-containing 66.50%, carbon containing 0.74%.
Table 1 comparative test result
As known from Table 1, after barite collecting agent prepared by employing the present invention, compare with conventional barite collecting agent, dosing reduces 25%, and in the situation that barite concentrate average grade is suitable, barium sulfate average recovery rate has improved 10.07%.Therefore, barite collecting agent collecting ability prepared by the present invention by force, selectively good, be specially adapted to sort carbon containing containing mud barite ore.
