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 collophane just-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 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 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 difficult choosing in all rocks phosphate in powder, wherein is the most difficult choosing with middle low grade collophanite again.Such ore is general to adopt positive and negative floatation process to handle.At present the collophane of commercial Application just-collecting agent in reverse floatation, require the flotation pulp temperature to reach more than 35 ℃ mostly, and selectivity is relatively poor, gained concentrate MgO content is higher, 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 collophane just-collecting agent in reverse floatation and preparation method thereof, when selected head grade 15% 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 normal temperature.
Technical scheme of the present invention is:
Collophane just-collecting agent in reverse floatation, it is characterized in that: mix 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.
Above-mentioned collophane just-collecting agent in reverse floatation in, 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 15% 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 has floatation indicators preferably 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.
