Abstract
The high iron slimed wulfenite floating process adopts sodium hexametaphosphate as dispersant, sodium hydroxide as ore pulp pH regulator, sodium sulfide for sulfurizing and deleading, copper sulfate as activator, kerosene as water repellent, isoamyl xanthate as wulfenite collector and 2# oil as foaming agent. The process can float to recover wulfenite with high iron content and serious sliming effectively. When the raw ore has Mo content of 0.5-0.76 %, Mo concentrate obtained through once coarse separation and four times of fine separation has Mo content of13-16.8 % and recovery rate up to 71-76 %.
Description
One, technical field
The present invention relates to a kind of mineral floating method, particularly a kind of high iron pelitization wulfenite floatation method.
Two, background technology
Chinese patent application NO.200610048650.9 discloses a kind of usefulness, and floating-heavy-floating combined process flow reclaims the method for wulfenite, is raw material with the wulfenite, and ore ore grinding to mineral monomer is dissociated; At first with floatation equipment and medicament molybdenum ore thing and gangue mineral are separated, the come-up product is the molybdenum concntrate product; Again with shaking table with molybdenum ore thing in the flotation tailing and gangue mineral further separate gravity treatment molybdenum concntrate product.When first section ore grinding deficiency so that during the abundant monomer dissociation of molybdenum ore thing,, make the further monomer dissociation of molybdenum ore thing with the further ore grinding of shaking table mine tailing, at last with floatation equipment and medicament further separate the molybdenum concntrate product; Floating agent vulcanized sodium, butyl xanthate, butyl ammonium aerofloat and pine tar.This invention is applicable to the wulfenite to be the molybdenum ore thing of main purpose mineral and separating of gangue mineral.But this invention long flow path and comparatively complicated needs multistage grinding, need desliming before the flotation, and the molybdenum ore thing rate of recovery is not high, only is 65%, and concentrate quality also has only 7.25%; In addition, this technological equipment investment is big, takes up an area of extensively, and energy consumption is bigger.In addition, the wulfenite to high ferro, argillization, microfine can't reclaim.
Three, summary of the invention
The object of the present invention is to provide and a kind ofly can improve the molybdenum concentrate grade and the rate of recovery, reduce the method for floating of the high iron pelitization wulfenite of energy consumption.
The present invention achieves the above object by the following technical solutions: as dispersant, NaOH is made pH values of pulp and is adjusted agent with calgon, vulcanizes with vulcanized sodium and takes off lead, and copper sulphate is made activator, and kerosene is made water-repelling agent, and isoamyl xanthate is made the wulfenite collecting agent.
Slurry pH is 9-10.5 during flotation; In the floatation process, after ore is milled to mineral monomer and dissociates, add sodium hexametaphosphate dispersant to agitator, hydro-oxidation sodium and vulcanized sodium are regulated pH then, add copper sulphate for activation molybdenum ore thing again, add collecting agent kerosene and isoamyl xanthate at last, No. 2 oil of foaming agent carry out collecting.
Dosing (g/t) is:
Calgon roughly selects 50～80 selected 20～50
Vulcanized sodium roughly selects 6000～9000 selected 1000～4000
Copper sulphate roughly selects 60～90 selected 0～1 0
Isoamyl xanthate roughly selects 250～300 selected 0～50
Kerosene roughly selects 60～80 selected 10～40
No. 2 oil roughly selects 0～60 selected 0～10
During use, be mixed with following concentration (weight %) earlier:
NaOH 10～20% aqueous solution
Calgon 1～5% aqueous solution
Vulcanized sodium 10～20% aqueous solution
Copper sulphate 1～5% aqueous solution
Isoamyl xanthate 1～5% aqueous solution
The direct stoste of kerosene is added
No. 2 the direct stoste of oil is added
When amount of sodium sulfide is 10000 g/t, when pH values of pulp was 10 left and right sides, the wulfenite floatation index was good; Add the dispersive property that calgon can improve ore pulp, but consumption then there is inhibitory action to wulfenite when excessive; Adopt copper sulphate the activated partial difficulty to float wulfenite, improved the rate of recovery of molybdenum; It is all relatively good to improving molybdenum concentrate grade and rate of recovery effect to make the wulfenite collecting agent with isoamyl xanthate, adds kerosene and can strengthen the hydrophobicity on wulfenite surface, improves the rate of recovery of molybdenum.
Concrete advantage of the present invention is:
1, adopts the present invention can effectively reclaim, and obtain the higher molybdenum concentrate grade and the rate of recovery low-grade high ferro wulfenite.Giving ore deposit molybdenum grade is being under 0.5～0.67% condition, through one roughing scan for twice and four times selected, molybdenum concentrate grade can reach 13～16.8%, the rate of recovery reaches 71～76%.
