Abstract
The invention discloses the methods that a kind of useless alum in ore treatment field extracts vanadic anhydride, comprising the following steps: (1), useless alum obtain filter residue and filtrate after water enchroachment (invasion) filters；(2), the filtrate is added KClO3 and carries out ion-exchange reactions, and VO2+ ion is become VO3- ion；(3), the solution after the exchange reaction is added NH4Cl and obtains NH4VO3；(4), the NH4VO3 obtains vanadic anhydride after roasting；By the way that useless alum is obtained filter residue and filtrate after water enchroachment (invasion) filters, filtrate is added after KClO3 carries out ion exchange and obtains VO3- ion, NH4VO3 is obtained after adding NH4Cl reaction, NH4VO3 obtains vanadic anhydride after roasting, in this way vanadic anhydride can be obtained from useless alum, the yield of vanadic anhydride is improved, the present invention can be used among the processing of useless alum.
Description
Technical field
The present invention relates to a kind for the treatment of of wastes produced method, in particular to a kind of method that useless alum extracts vanadic anhydride.
Background technique
Vanadium is a kind of high-melting-point refractory metal, and major product form has: vanadic anhydride, vanadium trioxide, vanadium
Iron, vanadium nitride etc..Wherein, vanadic anhydride and vanadium trioxide are most important vanadium oxides in actual production, they are to produce
The primary raw material of the subsequent vanadium product such as vanadium iron, vanadium nitride and vanadium carbide.The product of vanadium be divided into primary product, secondary product and
Three-level product.Primary product include contain vanadium mineral, concentrate, vanadium slag, the petroleum refining scrapped dead catalyst, the catalyst scrapped and
Other residues.Secondary product includes vanadic anhydride, is also possible to a kind of available industrial products, i.e., the catalyst of production sulfuric acid and
The catalyst of petroleum refining.Three-level product includes vanadium iron, vananum, molybdenum vananum, silicomanganese vanadium iron and vanadium chemical combination
Object, wherein vanadium iron is most important vanadium material, it accounts for the 85% of vanadium consumption figure.
Vanadic anhydride is widely used in the industries such as metallurgy, chemical industry, is mainly used for smelting ferrovanadium.As alloy addition, account for
80% or more of vanadic anhydride total flow, the annual consumption of vanadic anhydride is about at 400 tons or so, five oxygen of high-purity
Change the every annual requirement estimation of two vanadium at 100 tons or so.
Summary of the invention
The object of the present invention is to provide a kind of methods that useless alum extracts vanadic anhydride, by filtering useless alum by water enchroachment (invasion)
After obtain filter residue and filtrate, filtrate is added after KClO3 carries out ion exchange and obtains VO3- ion, adds after NH4Cl reaction
Vanadic anhydride is obtained after roasting to NH4VO3, NH4VO3, vanadic anhydride can be obtained from useless alum in this way, improve five
The yield of V 2 O.
To achieve the above object, the present invention provides a kind of methods that useless alum extracts vanadic anhydride, comprising the following steps:
(1), the alum that gives up obtains filter residue and filtrate after water enchroachment (invasion) filters；(2), the filtrate is added KClO3 and carries out ion-exchange reactions, will
VO2+ ion becomes VO3- ion；(3), the solution after the exchange reaction is added NH4Cl and obtains NH4VO3；(4), described
NH4VO3 obtains vanadic anhydride after roasting.
Compared with prior art, the beneficial effects of the present invention are by obtaining filter residue after water enchroachment (invasion) filters for useless alum
And filtrate, filtrate are added after KClO3 carries out ion exchange and obtain VO3- ion, obtain NH4VO3 after adding NH4Cl reaction,
NH4VO3 obtains vanadic anhydride after roasting, can obtain vanadic anhydride from useless alum in this way, improves vanadic anhydride
Yield, the present invention can be used among the processing of useless alum.
As a further improvement of the present invention, catalyst is added in the useless alum and carries out water enchroachment (invasion) filtering again, it can promote in this way
It is preferably dissolved into useless alum.
As a further improvement of the present invention, it is crushed after the useless alum addition catalyst and carries out water enchroachment (invasion) filtering again, this
Sample can allow useless alum preferably to dissolve.
As a further improvement of the present invention, the filter residue obtains filter residue and filtrate after carrying out reductic acid leaching filtration treatment,
The filtrate carries out the ion-exchange reactions, filter residue can effectively be used in this way, avoid the wasting of resources.
As a further improvement of the present invention, the filter residue is added NaSO3 and H2SO4 progress reductic acid and invades processing, in this way
The effect that acidification can be restored is more preferable.
As a further improvement of the present invention, the filter residue can make to avoid filter residue exhaust emission in this way with brickmaking
Environment.
As a further improvement of the present invention, the pH value of the ion-exchange reactions is 8, can make ion exchange in this way
The efficiency highest of reaction.
Detailed description of the invention
Fig. 1 is flow chart of the present invention.
Specific embodiment
The following further describes the present invention with reference to the drawings:
The method that a kind of useless alum as shown in Figure 1 extracts vanadic anhydride, comprising the following steps: (1), useless alum is by water enchroachment (invasion) filtering
After obtain filter residue and filtrate；(2), filtrate is added KClO3 and carries out ion-exchange reactions, and VO2+ ion is become VO3- ion；
(3), the solution after exchange reaction is added NH4Cl and obtains NH4VO3；(4), NH4VO3 obtains vanadic anhydride after roasting；It is useless
Catalyst is added in alum and carries out water enchroachment (invasion) filtering again；It is crushed after useless alum addition catalyst and carries out water enchroachment (invasion) filtering again；Filter residue carries out
Filter residue and filtrate are obtained after reductic acid leaching filtration treatment, filtrate carries out ion-exchange reactions；Filter residue be added NaSO3 and H2SO4 into
Row reductic acid invades processing；Filter residue can be with brickmaking；The pH value of ion-exchange reactions is 8.
When work, useless alum is added after catalyst to crush and carries out water enchroachment (invasion) and be obtained by filtration filter residue and filtrate, filter residue be added NaSO3 and
H2SO4 obtains filtrate and filter residue after carrying out reductic acid leaching filtration treatment, and filter residue can be added KClO3 and be carried out ion with brickmaking, filtrate
VO2+ ion is become VO3- ion by exchange reaction, and the solution after exchange reaction is added NH4Cl and obtains NH4VO3, NH4VO3 warp
