Description
Technical field
The present invention relates to mineral floating technical field, the method for purification of a kind of wollastonite.
Background technology
Wollastonite mine based on wollastonite, the impure mineral multidigit quartz of association and diopside etc., impurity Ore many in
In the granular solution gap being distributed in wollastonite, wollastonite, quartz and diopside broadly fall into silicate mineral, have the most similar
Character, therefore FLOTATION SEPARATION wollastonite, diopside and quartz have suitable difficulty.
Summary of the invention
It is an object of the invention to provide the method for purification of a kind of wollastonite, the method for purification of this wollastonite can solve silicon
The problem that lime stone, diopside separate with quartz difficulty.
In order to solve the problems referred to above, the technical solution used in the present invention is:
The method of purification of this wollastonite is with wollastonite mine as raw material, and described wollastonite mine comprises wollastonite, quartz and saturating brightness
Stone, wherein, the content of wollastonite is 56.2%～60.4%, and method of purification is:
Being pulverized by wollastonite mine, cross 100 mesh～140 mesh molecular sieves, obtain wollastonite in powder, adding water and making mass percent is 12%
～first pulp slurry of 17%, adding dispersant, magnetic separation removes impurity iron, and regulation liquid pH value, to 6.2～6.8, adds Colophonium
Amine makees collecting agent, wollastonite and diopside is floatingly selected, and obtains the first flotation thing, then adds water in the first flotation thing, is modulated into
Mass percent is second pulp slurry of 20%～25%, adds dodecyl salt acid amide and tannic acid, is flotated by wollastonite,
Obtain the second flotation thing, washing, dry；Wherein, the addition of dispersant is the 0.2%～0.5% of wollastonite in powder total amount；Rosin amine
Addition is wollastonite in powder total amount 0.05%～0.1%, the addition of dodecyl salt acid amide be wollastonite in powder total amount
