The invention discloses a kind of method that dual liquid flotation method removes iron in silica sand, comprise the following steps（1）Kaolin ore is tuned into aqueous solution ore pulp；（2）Add pH regulators；（3）Collecting agent is added after stirring, continues to size mixing；（4）Organic solution is added, then is sufficiently stirred；（5）Stratification, separation.The beneficial effect of the invention is：The Fe in silica sand can be made2O3Less than 0.15% is averagely down to by 0.172%.
Description
Technical field
The present invention relates to mineral purification technique field, the method for iron in specially a kind of dual liquid flotation method removing silica sand.
Background technology
In silica sand processing, it can not make using traditional ore-dressing technique (conventional gravity treatment, magnetic separation, flotation) in small, broken bits and ultra-fine
Impurity iron in broken silica sand powder is removed to standard content, and therefore, ore dressing worker looks for another way, and seeks unconventional silica sand and removes
Iron new method, impurity iron content in silica sand is substantially reduced, realize the deep processing of silica sand and greatly improving for economic value.
The content of the invention
It is an object of the invention to provide a kind of method that dual liquid flotation method removes iron in silica sand, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve the above object, the present invention provides following technical scheme：A kind of dual liquid flotation method removes the side of iron in silica sand
Method, comprise the following steps：
（1）Kaolin ore is tuned into aqueous solution ore pulp；
（2）Add pH regulators；
（3）Collecting agent is added after stirring, continues to size mixing；
（4）Organic solution is added, then is sufficiently stirred；
（5）Stratification, separation.
Preferably, the pH regulators are sodium carbonate.
Preferably, the collecting agent is tall oil.
Preferably, the step（2）PH value is 5.
Compared with prior art, the beneficial effects of the invention are as follows：The Fe in silica sand can be made2O3By 0.172% be down to 0.15% with
Under.
Embodiment
Below in conjunction with the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described,
Obviously, described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.Based in the present invention
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, all
Belong to the scope of protection of the invention.
The present invention provides a kind of technical scheme：A kind of method that dual liquid flotation method removes iron in silica sand, comprises the following steps：
（1）Kaolin ore is tuned into aqueous solution ore pulp；
（2）Sodium carbonate is added, adjusts PH to 5；
（3）Tall oil is added after stirring, continues to size mixing；
（4）Organic solution is added, then is sufficiently stirred；
（5）Stratification, separation.
Through many experiments, the Fe in silica sand can be made2O3Less than 0.15% is averagely down to by 0.172%.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of changes, modification can be carried out to these embodiments, replace without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
