Description
Technical field
The present invention relates to separation ore-sorting technical field, particularly relate to a kind of Muscovitum and the separation method of Anhydrite and beneficiation reagent.
Background technology
At present, in Muscovitum, Anhydrite Mineral separation technology, it is broadly divided into acid ore pulp cation according to the difference of collecting agent and catches
Receive agent floatation and alkalescence ore pulp anionic-cationic hybrid collector floatation.
Acid ore pulp cationic flotation method is to reclaim the effective ways of Muscovitum, due in cation-collecting agent flotation system, and cloud
Mother all has in the widest pH value range well can float domestic animal, and the silicate minerals such as Anhydrite are at cation-collecting agent flotation body
The pH value range in system with preferable floatability is relatively small, and floatability the most under strongly acidic conditions is poor, therefore,
Muscovitum can be realized under strong acidic condition separate with Anhydrite.In acid ore pulp environment when FLOTATION SEPARATION Muscovitum, Anhydrite, flotation
And need to add a large amount of hydrochloric acid during preparation amine medicament, and execute-in-place inclement condition, serious to equipment corrosion, flotation
Relatively costly.Wherein hydrochloric acid is the hydrochloride aqueous solution of variable concentrations, transparent colourless or yellow, and irritant abnormal smells from the patient is with strong
Corrosivity.The hydrochloric acid concentrated can form all mordant to the human tissue effect of acid mist, acid mist and hydrochloric acid solution, and damages
Evil respiratory apparatus, eyes, skin and the possibility of intestinal.When using hydrochloric acid, individual protective equipment should be coordinated, such as rubber gloves
Or the medicated clothing of polyvinyl chloride (PVC) gloves, protective eye lens, chemicals-resistant and shoes etc., to reduce the danger that directly contact hydrochloric acid is brought.
When in selected material containing sludge, it is effective for using alkalescence ore pulp anionic-cationic floatation sorting Muscovitum.
Pulp solids content during flotation is 40%～45%, makes adjustments agent with sodium carbonate and wooden calcium sulfonate, during flotation anion and
Cation-collecting agent is used in combination, and pH value is 8.0～10.5.In alkaline environment, floatation on mica concentrate is difficult to be dehydrated, and filters
Difficulty.
The method separated with Anhydrite for Muscovitum due to above two, be carried out, under acid or alkaline conditions in actual production
In have a bigger limitation, and prior art does not separate under the conditions of anacidity alkali-free the method for Muscovitum and Anhydrite.
Summary of the invention
It is an object of the invention to provide a kind of Muscovitum and the separation method of Anhydrite and beneficiation reagent, the method is in anacidity alkali-free condition
Lower flotation, safety simple to operate, separation costs is relatively low, also improves Muscovitum, the quality of Anhydrite separation.
It is an object of the invention to be achieved through the following technical solutions, the embodiment of the present invention provides a kind of Muscovitum to separate with Anhydrite
Method, this separation method includes:
Muscovitum and spectra are poured in flotation cell, adds high selective beneficiation reagent, and stir；Wherein, described choosing
The composition of ore deposit medicament is: lauryl amine 1.0～3.0 weight portion, octadecylamine 0.25～1.0 weight portion, diesel oil 1.0～2.0
Weight portion, isooctanol 1.0～2.0 weight portion；
Through one roughing, once purging selection, obtain being more than the feldspar concentrate of 95% containing spectra amount；
Muscovitum rough concentrate obtained by one roughing is carried out primary cleaning, obtains being more than containing mica mineral amount the Muscovitum essence of 95%
Ore deposit.
In above-mentioned separation method, the concrete mode through one roughing, once purging selection is:
Under the conditions of natural ph, to the Muscovitum in the described flotation cell after adding high selective beneficiation reagent and stirring and
Spectra carries out one roughing and obtains Muscovitum rough concentrate；
Continue in described flotation cell, add high selective beneficiation reagent, and stir, carry out once under the conditions of natural ph
Scanning, after scanning, the product in described flotation cell is described feldspar concentrate；
Described Muscovitum rough concentrate obtained by one roughing is carried out primary cleaning concrete mode be:
Muscovitum rough concentrate obtained by one roughing is poured in another flotation cell, and stirs, carry out under the conditions of natural ph
Primary cleaning, selected rear obtained froth pulp is described Muscovitum concentrate.
In above-mentioned separation method, Muscovitum with spectra is: containing mica mineral amount 18.93%～77.62%, spectra amount
The raw ore of 21.57%～80.55%.
The embodiment of the present invention also provides for the separation ore-sorting medicament of a kind of Muscovitum and Anhydrite, and this beneficiation reagent is composed of the following components:
Lauryl amine 1.0～3.0 weight portion, octadecylamine 0.25～1.0 weight portion, diesel oil 1.0～2.0 weight portion, different pungent
