Abstract
The invention discloses a kind of composite inhibitor for copper arsenic mineral separating flotation, the composite inhibitor is uniformly mixed by the raw material of following mass fraction using conventional method: Na2S2O8It is 8-15 parts, Na for 80-93 parts, sodium humate5P3O10It is 8-20 parts；This composite inhibitor has the function of elimination activity to the copper ion contained in mineral and the copper ion generated in the separation of copper arsenic, reaches good copper arsenic separating effect, and be simple to manufacture, be at low cost.
Description
Technical field
The present invention relates to copper arsenic mineral separating flotation fields, and in particular to a kind of for the compound of copper arsenic mineral separating flotation
Inhibitor.
Background technique
Copper is the non-ferrous metal very close with human relation, not only resourceful in nature and have and more excellent lead
The advantageous properties such as electrical property, thermal conductivity, ductility, corrosion resistance, wearability are widely used in electric power, electronics, the energy and stone
Change, mechanical and metallurgy, traffic, light industry, new industry and wait fields.Most copper mine mainly based on sulphide ore, wherein
Copper sulfide mineral mainly has chalcopyrite, atacamite, vitreous copper, tennantite, bornite, chessy copper etc..Copper ion is arsenic mineral
The efficient activator of flotation, the presence of copper ion increase the floatability of arsenic mineral, improve the content of arsenic in copper ore flotation,
To keep arsenic content in selected copper mine exceeded.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of composite inhibitors for copper arsenic mineral separating flotation.
The present invention is solved the above problems using following technical scheme: a kind of compound inhibition for copper arsenic mineral separating flotation
Agent, the composite inhibitor are made of following raw material according to mass fraction meter:
Na2S2O8 80-93 parts
8-15 parts of sodium humate
Na5P3O10 8-20 parts
Wherein Na2S2O8For regulator, Na5P3O10For dispersing agent, sodium humate is inhibitor；
In a preferred embodiment of the invention, according to mass fraction meter, it is made of following raw material:
Na2S2O8 87 parts
10 parts of sodium humate
Na5P3O10 15 parts；
Further, it according to mass fraction meter, is made of following raw material:
Na2S2O8 80 parts
8 parts of sodium humate
Na5P3O10 20 parts；
Composition of the invention is uniformly mixed using conventional method.
The beneficial effects of the present invention are:
The Copper ore containing arsenics objects such as the inhibition enargite of the composite inhibitor property of can choose of the invention, tennantite, pass through reduction
Copper ion in ore pulp reduces copper to the activation of arsenic, while by forming hydrophily oxidation film pair on Copper ore containing arsenic surface
The inhibiting effect that Copper ore containing arsenic object plays is realized to not Copper ore containing arsenic object and the sulphur such as vitreous copper, bornite, chessy copper, atacamite
The Selective Separation of the arsenic-containing ores such as domeykite, tennantite reduces the content of arsenic in copper concentrate, makes flotation concentrate arsenic content
It is up to standard, reduce the damage to equipment and the pollution to environment.Composite inhibitor cost of manufacture of the invention is cheap, storage side
Formula is simple, and using effect is good.
Detailed description of the invention
Fig. 1 is the process flow chart of the embodiment of the present invention.
Appended drawing reference: a '-lime；B '-Isobutylxanthic acid；- No. 2 oil of c '.
Specific embodiment
Below with reference to embodiment and attached drawing, the present invention is described in further detail.
It is tested in the embodiment of the present invention using the ore of Chifeng's tailing different phase, the main ore of Chifeng's tailing
Ingredient is enargite.
Implementing procedure explanation of the invention:
As shown in Fig. 1, inhibitor of the present invention and raw ore are added in ball mill, be added clear water and lime a ' 1600g/t into
Row ore grinding, until grinding fineness is that -0.075mm accounts for 70%, ore milling concentration 60%；The ore pulp of milled is added in 3L flotation cell,
It calculates, stirs 5 minutes by tcrude ore dry weight per ton, successively add Isobutylxanthic acid b ' 10g/t, No. 2 oil c ' 5g/t, stirring is sized mixing
First time copper roughing I is carried out after 10min, obtains separating flotation concentrate product and tailing, concentrate product copper roughing foam is through primary
Blank is selected to obtain low arsenical copper concentrate 1 and cleaner tailings；
The tailing of roughing I and cleaner tailings are mixed, add lime a ' 80g/t, investment ball mill carries out ore grinding, until grinding fineness
85% is accounted for for -0.041mm；Isobutylxanthic acid b ' 10g/t, No. 2 oil c ' 5g/t are successively added, stirs to size mixing and carries out the after 10min
Secondary copper roughing II obtains selected product and tailing；
Isobutylxanthic acid b ' 10g/t, No. 2 oil c ' 5g/t are added in the tailing of roughing II, are carried out for the first time after stirring the 10min that sizes mixing
I is scanned, scavenger concentrate and tailing are obtained, carries out the selected work of copper twice after scavenger concentrate and the selected product of roughing II are merged
Industry, obtains low arsenical copper concentrate 2, and the selected operation tailing of copper successively returns to upper level flotation operation；
The tailing for scanning I is sequentially added into Isobutylxanthic acid b ' 10g/t, No. 2 oil c ' 5g/t, stirring, which is sized mixing, carries out the after 10min
It is secondary to scan II, scavenger concentrate and tailing are obtained, gained scans II concentrate and returns to II flotation operation of roughing；
II gained tailing will be scanned and sequentially add Isobutylxanthic acid b ' 10g/t, No. 2 oil c ' 5g/t, carried out after stirring the 10min that sizes mixing
Third time scans III, obtains scavenger concentrate and tailing, scans III tailing as true tailings product output, concentrate returns to upper level
Flotation operation.
