Abstract
The invention relates to a novel efficient collophanite reverse flotation collecting agent. A process comprises the following steps: (1) performing a saponification reaction on a fatty acid mixture in which the content of fatty acid with 16-18 carbon chains accounts for greater than or equal to 75 percent of the total content of fatty acid to obtain water-soluble sodium fatty acid; (2) diluting a mixture dispersing agent consisting of multiple polyphosphates with water into a solution of which the mass percent is 1-50 percent; (3) uniformly mixing the sodium fatty acid obtained in the step (1) and the dispersing agent solution obtained in the step (2) by stirring according to the proportion of greater than 5:1 to obtain the novel efficient collophanite anti-flotation collecting agent; (4) applying the obtained novel efficient collophanite anti-flotation collecting agent to anti-flotation operation. Compared with the conventional collophanite anti-flotation collecting agent, the novel efficient collophanite reverse flotation collecting agent has the advantages that phosphoric acid serving as an inhibitor does not need to be added under the condition that each flotation index is approximate, the using amount of the collecting agent is reduced by over 20 percent in comparison to that of the conventional collophanite reverse flotation collecting agent, and the cost of a collophanite reverse flotation agent is lowered greatly. The efficient collophanite reverse flotation collecting agent is economical and environmental friendly, and is suitable to be popularized and used.
Description
Technical field
The present invention relates to a kind of new and effective Collophane anti-floatation collector, particularly relate to a kind of collophane reverse flotation that improves and remove the dispersed and new and effective collecting agent optionally of carbonate mineral.
Background technology
The main application of rock phosphate in powder is the phosphate fertilizer of using as agricultural production grain, so cause its added value relatively low.Along with the day by day dilution of rock phosphate in powder and the sharply rising of cost of winning, and phosphorus concentrate price is relatively low, make flotation cost always in lower cost space, therefore need to research and develop good dispersion, selectively strong, the efficient collophane reverse flotation that consumption is low is deviate from the collecting agent of carbonate mineral.
Summary of the invention
The object of the invention is to overcome above-mentioned prior art deficiency, a kind of new and effective Collophane anti-floatation collector is provided, it can improve the dispersiveness of collecting agent with selective, reduces collector dosage, is all suitable collecting agents of promoting the use of of a kind of economy, environmental protection.
The technical solution adopted in the present invention is:
A kind of Collophane anti-floatation collector contains following composition:
(1) fatty acid sodium salt soluble in water, this fatty acid sodium salt is to obtain by saponification taking carbochain as the fatty acid mixed that 16 ~ 18 aliphatic acid accounts for more than total fatty acid content >=75%;
(2) dispersant solution, the mixture dispersant that this dispersant solution is made up of multiple Quadrafos, is diluted with water to the solution of mass percent 1 ~ 50%;
(3) dispersant solution in fatty acid sodium salt in (1) and (2), in the ratio mixing and stirring that is greater than 5:1, is obtained to Collophane anti-floatation collector.
The invention has the beneficial effects as follows:
1. the efficient collecting agent in reverse floatation of collophane, has improved the dispersiveness of collecting agent with selective.
2. in reverse flotation work, need not add inhibitor phosphoric acid.
3. beneficiation cost is low, easily realizes suitability for industrialized production, remarkable in economical benefits.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is further illustrated, but be not limited to embodiment.In an embodiment, apart from special instruction, all percentage compositions are mass percent.Collophane anti-floatation collector contains following composition:
(1) fatty acid mixed accounting for more than total fatty acid content >=75% taking carbochain as 16 ~ 18 aliphatic acid obtains fatty acid sodium salt soluble in water by saponification;
(2), by a kind of mixture dispersant being formed by multiple Quadrafos, be diluted with water to the solution of mass percent 1 ~ 50%;
(3) dispersant solution in fatty acid sodium salt in (1) and (2), in the ratio mixing and stirring that is greater than 5:1, is obtained to a kind of new and effective Collophane anti-floatation collector;
The new and effective collophane collecting agent obtaining is used for to reverse flotation work, compared with conventional Collophane anti-floatation collector, in the situation that flotation indices is close, can add inhibitor phosphoric acid, and this collector dosage reduces more than 20% than conventional Collophane anti-floatation collector consumption, greatly reduce collophane reverse floatation agent cost.And this collector dosage reduces greatly than conventional Collophane anti-floatation collector consumption, effectively reduce collophane reverse floatation agent cost.
