Description
Technical field
The present invention relates to a kind of Collophanite de-magging collector and preparation method thereof.
Background technology
China's phosphate rock resource is abundant, but low-grade collophane mineral deposit in mostly being greatly, the rich ore reserves are few.Along with the output of domestic high concentration phosphorus composite fertilizer constantly increases, to P
2O
5Also constantly increasing of the phosphorus ore demand of content more than 30%, the flotation of middle low grade collophanite is imperative.And the fine or not key of middle low grade collophanite flotation technology index is the performance of collecting agent.
Summary of the invention:
The object of the present invention is to provide a kind of Collophanite de-magging collector and preparation method thereof, this Collophanite de-magging collector can significantly improve phosphorus content by flotation with collophane, and magnesium content significantly descends; Simple, the easily realization of this preparation method.
To achieve these goals, technical scheme of the present invention is: a kind of Collophanite de-magging collector, it is characterized in that it is that 15-45% caustic soda feedstock production forms by oleic acid, the concentrated sulfuric acid and mass concentration mainly, the shared mass fraction of each raw material is: 1 part of oleic acid, concentrated sulfuric acid 0.1-0.5 part, mass concentration are 15-45% caustic soda 0.3-0.8 part.
The preparation method of above-mentioned a kind of Collophanite de-magging collector is characterized in that it comprises the steps:
1) by the shared mass fraction of each raw material be: 1 part of oleic acid, concentrated sulfuric acid 0.1-0.5 part, mass concentration are that to choose oleic acid, the concentrated sulfuric acid and mass concentration be 15-45% caustic soda raw material for standby to 15-45% caustic soda 0.3-0.8 part;
2) with oleic acid and the concentrated sulfuric acid at 10-40 ℃ of following isothermal reaction 10-70min, adding mass concentration down at 20-60 ℃ then is the 15-45% caustic soda, is warming up to 70-110 ℃ of isothermal reaction 1-5h, product.
The present invention adopts oleic acid, the concentrated sulfuric acid and caustic soda common used in industry raw material synthetic under simple process conditions, and this technology is not high to equipment and operating personnel's requirement, and the present invention realizes easily.Beneficial effect of the present invention is as follows:
1) Collophanite de-magging collector selectivity of the present invention is good, can raw ore is phosphorous 19.00%, containing the collophane of magnesium more than 10.00%, to bring up to concentrate by flotation phosphorous more than 37.00%, and contain magnesium below 1.20%, and the rate of recovery is (this index is all and reelects index, and Collophanite de-magging collector of the present invention has passed through continuity test) more than 85%.And Collophanite de-magging collector amount ratio General Medicine of the present invention reduce about 20%.
2) Collophanite de-magging collector of the present invention can descend flotation at low temperature (below 10 ℃), and does not influence mineral processing index.
3) Collophanite de-magging collector synthesis technique of the present invention is simple, equipment investment is few, is fit to extensively promote.
