The present invention relates to a kind of efficiently except the rock phosphate in powder collecting agent in reverse floatation of calcite, by mass percentage, by 80～90% modified fat acid and 10～20% complexed surfactant compounding form；Wherein modified fat acid is formed by 50% turkey red oil and 50% trihydroxy ethylamine oleate soap are compounding, and complexed surfactant is compounded formed by 20% sulfonated oil, 30% fatty alcohol-polyoxyethylene ether AEO 3,20% Palmic acid formicester sodium sulfonate, 30% alhpa olefin sodium sulfonate.The present invention is applicable to phosphorite and removes the reverse floatation process of calcite, has selectivity excellent, the feature that the concentrate response rate is high.
Description
Technical field
The present invention relates to a kind of rock phosphate in powder collecting agent in reverse floatation, especially relate to efficiently remove calcite from rock phosphate in powder
Collecting agent.Belong to surfactant field.
Background technology
Phosphorus ore is important strategic resource, is mainly used in and prepares phosphate and phosphate fertilizer.The production of phosphate and phosphate fertilizer is right
The requirement of rock phosphate in powder raw material is P2O5Content is more than 30%, and content of MgO is below 2%.In nature, it is possible to reach so to refer to
Target rock phosphate in powder is limited, and most mid low grade phosphate rock stone needs to carry out ore dressing, to reaching the requirement of high-quality rock phosphate in powder.Foam floats
Choosing is a kind of ore dressing mode that current sulphur dioxide of phosphor chemical industry should be with the most use, the most general except the technique of dolomite with reverse flotation the most again
Time.This technique is only applicable to the phosphorite that dolomite content is higher.Nature exists dolomite content is relatively low, calcite content
Higher Sedimentary phosphate rock.For such Ore, maximally effective ore dressing mode is to remove calcite by reverse flotation, makes final
P in concentrate2O5Content is promoted to more than 30%.Except the collecting agent of calcite plays conclusive effect in this floatation process.Cause
This, developing a kind of has certain using value except the rock phosphate in powder collecting agent in reverse floatation of calcite.
Summary of the invention
It is an object of the invention to provide a kind of efficiently except the rock phosphate in powder collecting agent in reverse floatation of calcite, dolomite is contained
Measure relatively low and that calcite content is higher phosphorite, by reverse floatation process, the collecting agent of the application present invention, remove calcite,
Can be by the P in concentrate2O5Content is promoted to more than 30%, has fine selectivity, the feature that the concentrate response rate is high.
The technical scheme is that
1, a kind of efficiently except the rock phosphate in powder collecting agent in reverse floatation of calcite, by mass percentage, by 80～90% change
Property fatty acid and 10～the complexed surfactant of 20%, by the way of compounding, obtains final products.
2, the acid of the modified fat in above-mentioned 1 by 50% turkey red oil and 50% trihydroxy ethylamine oleate soap compounding and
Become.
3, the complexed surfactant in above-mentioned 1 by 20% sulfonated oil, the fatty alcohol-polyoxyethylene ether AEO 3 of 30%,
The Palmic acid formicester sodium sulfonate of 20% and 30% alpha-olefin sodium sulfonate compound and form.
4, the alpha-olefin sodium sulfonate in above-mentioned 3, carbon number distribution is C14 or C16.
The present invention is applicable to phosphorite and removes the reverse floatation process of calcite, has selectivity excellent, the high spy of the concentrate response rate
Point.
