Abstract
The invention relates to a collophanite obverse-reverse flotation collecting agent and a preparation method thereof. The collophanite obverse-reverse flotation collecting agent provided by the invention is prepared by mixing basic substances with water; the mass ratio of the basic substances to the water is 1:(20-100), wherein the basic substances comprise the following components in percentage by weight: 90-95% of higher fatty acid soap and 5-10% of dodecyl phosphate ester; and the content of fatty acid in the higher fatty acid soap is not less than 40%. The collophanite obverse-reverse flotation collecting agent provided by the invention has the characteristics of low selected raw ore grade, wide application range and high concentrate recycling rate. Compared with the prior art, the collophanite obverse-reverse flotation collecting agent provided by the invention has the advantages of good selectivity, low cost and suitability for low-grade collophanite flotation at normal temperature.
Description
Technical field
The present invention relates to a kind of Collophanite obverse-reverse flotation collecting agent and preparation method thereof.
Background technology
Phosphorus ore is 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 higher, and MgO content is more low better.General high-quality rock phosphate in powder P
2O
5Content is more than 30%, and MgO content is below 2%.Occurring in nature, the rock phosphate in powder that can reach index like this is limited, and mid low grade phosphate rock stone need to carry out ore dressing mostly, in the hope of reaching the requirement of high-quality rock phosphate in powder.Collophane is a kind of of relatively difficult choosing in all rocks phosphate in powder, wherein again with mid-low grade collophanite ore for the most difficult choosing.Such ore is general to adopt positive and negative floatation process to process.The Collophanite obverse-reverse flotation collecting agent of commercial Application requires the flotation pulp temperature to reach more than 35 ℃ mostly at present, and selectively relatively poor, and gained concentrate MgO content is higher, and the concentrate rate of recovery is on the low side.
Summary of the invention
The object of the present invention is to provide a kind of Collophanite obverse-reverse flotation collecting agent and preparation method thereof, when selected head grade 15% when above, the product of producing still can reach the qualified concentrate containing index.And the concentrate rate of recovery is high, and concentrate MgO content is low, and beneficiation cost is low; In addition, reasonable separating effect is arranged under the normal temperature.
Technical scheme of the present invention is:
Collophanite obverse-reverse flotation collecting agent is characterized in that: 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: content of fatty acid is not less than 40% higher fatty acids soap 90～95%, and 1-isobutyl-3,5-dimethylhexylphosphoric acid 5～10%, each component are by weight percentage.
Described higher fatty acids soap is got by the unsaturated high-grade fatty acid saponification of the C18 of the saturated higher fatty acid of 10～20% C12-C18 and 80～90%, and the saturated higher fatty acid of C12-C18 and the unsaturated high-grade fatty acid of C18 are by weight percentage.
In the above-mentioned Collophanite obverse-reverse flotation collecting agent, described higher fatty acids soap is 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 15% when above, and the product of producing still can reach the qualified concentrate containing index.This has very important effect for the utilization of a large amount of low-grade phosphate ore stone resource of China.The present invention also has the characteristics that the concentrate rate of recovery is high, concentrate MgO content is low, beneficiation cost is low.The present invention has preferably floatation indicators when being warmed up to more than 35 ℃, and under the normal temperature, floatation indicators still can reach production requirement.The present invention not only be applicable to collophane just-reverse flotation, and during the normal temperature flotation that can be applied to various rocks phosphate in powder produces.
