Abstract
The invention relates to a collophane low-temperature reverse flotation collector and a preparation method thereof. The collector is prepared by mixing basic substance with water in a weight ratio of 1:20-100, wherein the basic substance comprise the following components by weight percent: 90-95% of higher fatty acid soap with the fatty acid content of no less than 40% and 5-10% of terpenol. The collector is characterized in that the grade of the selected crude ore is low, the applicable scope is wide, the recovery rate of the concentrate is high, the MgO content of the concentrate is low and the cost of ore dressing is low. Compared with the prior art, the gelation of the collector is difficult to appear below 10 DEG C, the flotation index is qualified and the collector can adapt to the low-temperature flotation.
Description
Technical field
The present invention relates to a kind of collophane low temperature collecting agent in reverse floatation and preparation method thereof.
Background technology
Phosphorus ore is the important strategic resource, is mainly used in preparation phosphate and phosphate fertilizer.The production of phosphate and phosphate fertilizer is P to the requirement of rock phosphate in powder raw material
2O
5Content is high more, and MgO content is low more good more.General high-quality rock phosphate in powder P
2O
5Content is more than 32%, and MgO content is below 1%.Occurring in nature, the rock phosphate in powder that can reach index like this is limited, and most low-phosphorous high-magnesium-phosphorus ore stone need carry out ore dressing, in the hope of reaching the requirement of high-quality rock phosphate in powder.The collecting agent that uses in the floating separation technology has reasonable separating effect under the normal temperature at present.But when water temperature was lower than 10 ℃, collecting agent easily formed micelle, active decline, and production target does not reach requirement.
Summary of the invention
The object of the present invention is to provide a kind of collophane low temperature collecting agent in reverse floatation and preparation method thereof, when selected head grade 21% when above, the product of being produced still can reach the qualified concentrate containing index.And concentrate rate of recovery height, concentrate MgO content is low, and beneficiation cost is low; In addition, reasonable separating effect is arranged under the low temperature.
Technical scheme of the present invention is:
Collophane low temperature collecting agent in reverse floatation is mixed by base substance and water; The mass ratio of base substance and water is 1: 20～100; Wherein the component of base substance is that content of fatty acid is not less than 40% higher fatty acids soap 90～95%, terpenol (BK201) 5～10%.
In the above-mentioned collophane low temperature collecting agent in reverse floatation, described higher fatty acids soap is got by 50～60% saturated higher fatty acid and 40～50% unsaturated high-grade fatty acid saponification.
In the above-mentioned collophane low temperature collecting agent in reverse floatation, described higher fatty acids soap is a potash soap.
Compared with the prior art, the present invention has adopted new material component.The selected head grade of collecting agent of the present invention is 21% when above, and the product of being produced still can reach the qualified concentrate containing index.This has important effect for the utilization of a large amount of low-grade phosphate ore stone resource of China.The present invention also has concentrate rate of recovery height, concentrate MgO content is low, beneficiation cost is low characteristics.The present invention not only has floatation indicators preferably under the normal temperature, is lower than 10 ℃ in temperature, and floatation indicators still can reach production requirement.The present invention not only is applicable to the flotation at low temperature production of collophane, and can be applied in the flotation at low temperature production of various rocks phosphate in powder.
