Phosphate minerals, in the groove of flotation desliming operation, product is again with crossing the machinery desliming most clay class silicate mineral of removing, then enters
The follow-up Counterfloatating desiliconization operation of row.
A kind of two step desliming reverse floatation process processing high alumina-silica collophane of the present invention, its concrete steps are such as
Under:
(1) high alumina-silica collophane is fed broken and grinding operation, treat that valuable mineral and gangue mineral realize monomer solution substantially
Add water after from and size mixing, feed desliming agitator tank, in agitator tank, be separately added into dispersant waterglass and fatty acid soaps collecting agent
Size mixing；
(2) pulp gravity flow sized mixing, in de slime flotation groove, carries out flotation desliming operation, and the froth pulp of gained predominantly may be used
The preferable high-grade phosphorus concentrate of buoyancy, gives to the dense system of concentrate, and in groove, product is mainly silicoide and floatability is poor
Phosphorus ore containing；
(3) in the groove of de slime flotation, product feeds cyclowass and carries out secondary desliming, and the overflow product of cyclone is given to mine tailing
Concentrator, the sand setting product of cyclone feeds Counterfloatating desiliconization agitator tank；
(4) add amine collector in Counterfloatating desiliconization stirring, give to reverse flotation flotation cell after sizing mixing, carry out Counterfloatating desiliconization work
Industry, the froth pulp of gained is mainly gangue mineral, and through transport pump to mine tailing concentrator, in groove, product is given to the dense system of concentrate
System；
In reverse flotation groove, product and the foams mix of de slime flotation groove are as final concentrate.
In a kind of two step desliming reverse floatation process processing high alumina-silica collophane of the present invention, it is further preferred
Technical scheme be:

SiO2Mass content is 17% ~ 31%, Al2O3Mass content is 4.5% ~ 9%.By present invention process, it is possible to obtain in collophane concentrate
P2O5Grade is 28% ~ 36%, and MgO mass content is 0.3% ~ 1.5%, Al2O3Mass content is 0.8% ~ 3.2%.
The principle of the present invention is: the low grade of high alumina siliceous collophane Ore Mineral Component is single, with low carbonate fluorine apatite
Being main, a small amount of carbonatoapatite, apatite, gangue mineral mainly has quartz, Anhydrite, kaolinite, Muscovitum, hydromica (illite)
Deng, P2O5More uniform at each grain class distribution ratio of raw ore, and in raw ore, clay silicate mineral content is higher, is carrying out reverse flotation
During desiliconization operation, if directly using machinery desliming, while abjection clay mineral, also can remove a part of valuable mineral, cause
Concentrate P2O5The response rate is relatively low.
Compared with prior art, present invention process increases by one direct flotation flotation desliming operation before machinery desliming operation,
Selecting major part by flotation and have been carried out the fine-graded phosphorus ore containing of monomer dissociation, this part phosphorus ore containing floatability is relatively
Good, concentrate grade can directly reach more than 29%, and in the groove of flotation desliming operation, product is again with crossing machinery desliming removing major part
Clay class silicate mineral, significantly improve the flotation environment of follow-up Counterfloatating desiliconization operation, greatly reduce reverse flotation
The dosing of desiliconization operation.Compared with using single direct floatation process, having mog relatively thick, dosing is less, choosing
The lower-cost advantage in ore deposit.
