Abstract
The present invention relates to the collecting agent of carbonate mineral in a kind of efficient removal collophane.Present invention process is: (1) by carbochain be 18 oleic acid and the linoleic acid content aliphatic acid that is greater than 65% carry out saponification; (2) by saponified 40 ~ 50 DEG C time, the phthalic acid diethylester adding 5 ~ 25% by mass percentage carries out emulsification, namely obtains the collecting agent of carbonate in efficient removal collophane; (3) this collecting agent is used for collophane reverse flotation collecting carbonate mineral, when adding identical collector dosage and being close with content of MgO in acquisition concentrate, compared with the fatty acid soaps flotation (flotation time 7 minutes) not adding phthalic acid diethylester, flotation time shortens more than 36%, and the flotation rate of carbonate mineral improves more than 20%.
Description
Technical field
The present invention relates to the collecting agent of carbonate mineral in a kind of efficient removal collophane.
Background technology
Along with the high speed development of Phosphate Fertilizer Industry, exploitation and the consumption of phosphorus ore also sharply rise, and the overall grade of phosphorus ore declines day by day, and the rock phosphate in powder of more than 90% needs could obtain phosphorus concentrate for phosphoric acid production by flotation.And flotation needs a large amount of raw material of fatty acid, aliphatic acid is due to relative low price, but dispersed bad, selective poor, causes flotation time long, flotation speed slowly, the equipment causing flotation to need and space large.For this reason, research is needed efficiently can to deviate from the collecting agent of carbonate mineral.
Summary of the invention
The object of the invention is to overcome prior art deficiency, there is provided the collecting agent of carbonate mineral in a kind of efficient removal collophane, it improves the dispersiveness of collecting agent, and greatly shortening flotation is the time, improving flotation speed, is all suitable collecting agent promoted the use of of a kind of economy, environmental protection.
The technical scheme that in a kind of efficient removal collophane of the present invention, the collecting agent of carbonate mineral adopts is:
(1) by carbochain be 18 oleic acid, the linoleic acid aliphatic acid that accounts for total content 65% carry out saponification;
(2) fatty acid soaps that saponification obtains is mixed with phthalic acid diethylester, wherein phthalic acid diethylester accounts for 5 ~ 25% of mixture gross mass, fatty acid soaps accounts for 75 ~ 95% of mixture gross mass, 40 ~ 50 DEG C of constant temperature emulsifications 1 ~ 1.5 hour, namely obtain the collecting agent removing carbonate in collophane.
This collecting agent is used for collophane reverse flotation collecting carbonate mineral, when adding identical collector dosage and being close with content of MgO in acquisition concentrate, compared with the fatty acid soaps flotation (flotation time 7 minutes) not adding phthalic acid diethylester, flotation time shortens more than 36%, and the flotation rate of carbonate mineral improves more than 20%.
The invention has the beneficial effects as follows:
1. the collecting agent of carbonate mineral in a kind of efficient removal collophane.
2. substantially reduce flotation time, improve flotation speed and collecting agent dispersiveness.
3. beneficiation cost is low, easily realizes suitability for industrialized production, remarkable in economical benefits.
