Description
Technical field
The invention belongs to beneficiation collecting agent technical field, it is related to a kind of low-temperature instant type rock phosphate in powder flotation collector and preparation
Method.
Background technology
Most of rocks phosphate in powder select factory to be equipped with sulfuric acid plant, can be heated using the steam generated in sulphuric acid process
It makes up a prescription.But still there is portion's separating plant there was only ore dressing plant on Guizhou, Sichuan and other places, without steam, need to add using electricity during making up a prescription
Hot pin heating water makes up a prescription.Not only the efficiency of heating surface is low for this method, and heating speed is slow, and conventional fatty acid is caused to be caught
Receiving agent cannot be completely dissolved, and cause flotation collector consumption high.More seriously normal fat acid collector is at low temperature
Easy gel blocks pipeline, causes that factory is selected to stop.
Therefore, a kind of low-temperature instant type rock phosphate in powder flotation collector is developed, to selecting factory that flotation is overcome to catch without steam-heated
The problem for receiving agent dissolving is of great significance.
Invention content
The purpose of the present invention aiming at dissolution in low temperature efficiency existing for above-mentioned flotation collector, catch by low, high energy consumption and flotation
The problems such as agent consumption is high and equipment failure rate is high is received, a kind of low-temperature instant type rock phosphate in powder flotation collector and preparation method are provided,
Flotation collector dissolution in low temperature speed provided by the invention is fast, and under the conditions of 40 DEG C, the collecting agent solution that mass concentration is 5% can be
Dissolving in 40min, and low temperature aeneficiation effect is good, still there is good aeneficiation effect at 20 DEG C, reduces energy consumption；Low temperature not gel, drop
Factory's production capacity is selected in low equipment failure rate, raising.
The technical scheme is that：
A kind of low-temperature instant type rock phosphate in powder flotation collector, each component is based on quality percentage, it is characterised in that：By 40~
44% polyhydrony fatty acid, 25~27% oleic acid, 22~24% water, 5~13% AEO3 are added in reaction kettle, 70
~90 DEG C are stirred 20~40min and mixed material are made；The quality for accounting for mixed material 25-35% is added in mixed material
A concentration of 30% soda bath, controlling reaction temperature continue insulation reaction 100-140min at 90-100 DEG C；It is cooling to be made low
Warm Instant rock phosphate in powder flotation collector.
A kind of preparation method of low-temperature instant type rock phosphate in powder flotation collector, based on quality percentage, feature exists each component
In：(1) by 40~44% polyhydrony fatty acid, 25~27% oleic acid, 22~24% water, 5~13% AEO3 be added
In reaction kettle, it is stirred 20~40min at 70~90 DEG C, mixed material is made；(2) it is added in mixed material and accounts for mixture
Expect that the mass concentration of 25-35% is 30% soda bath, controlling reaction temperature continues insulation reaction 100- at 90-100 DEG C
140min；(3) cooling, obtain low-temperature instant type rock phosphate in powder flotation collector.
The polyhydrony fatty acid is 9,10- dihydroxystearic acids or 9,10,12,13- tetrahydroxys aliphatic acid or the two
Mixture.It can directly purchase, can also be prepared by existing production technology oneself.
30% above-mentioned soda bath, can be commercially available 30% soda bath, can also be that high-concentration alkali liquor is dilute
30% soda bath being prepared is released, can also be that 30% soda bath that water is formulated is dissolved in by solid caustic soda.
Using the beneficial effects of the invention are as follows：
Flotation collector dissolution in low temperature speed is fast, for example, this flotation collector is at 40 DEG C, mass concentration is 5% to catch
Receiving agent solution can be completely dissolved in 40min.The flotation collector that solution rate uses more now promotes 50~100%.
Flotation collector low temperature aeneficiation effect is good.The flotation flotation collector that rock phosphate in powder flotation at present uses is mostly aliphatic acid
Class, bad dispersibility need slurry temperature just to have greater activity at 30~35 DEG C, and use the beneficiation collecting agent of the present invention at 20 DEG C
It is lower to have preferable aeneficiation effect.
Flotation collector is not easy gel.There are gelatin phenomenon, poles for the fatty acid collecting agent that rock phosphate in powder flotation at present uses
Pipeline and delivery pump are easily blocked, causes non-normal stop, reduction to select factory's production capacity, increases beneficiation cost.And use the choosing of the present invention
Mine collecting agent in process of production, does not occur producing parking phenomenon caused by gel at 20 DEG C.
Core of the invention innovative point is the polyhydrony fatty acid for referring to have polyhydroxy group, can not only reduce collecting
The krafft point of agent enhances its dissolubility, and the collecting agent also has stronger lime soap dispersing power, resistance to hard water strong.
