Description
Technical field
The invention belongs to electrochemical fields, are related to a kind of method of electrolysis method Leaching Vanadium from vanadium iron spinellid,
Vanadium iron spinel-type concentrate containing vanadium is especially made into soluble anode Direct Electrolysis in oxalic acid electrolyte solution, is obtained containing vanadium
Leachate.
Background technique
Vanadium is a kind of important alloying element, is widely used in the industries such as machinery, aviation, electronic technology, national defense industry, because
This its production is concerned.Currently, the source of vanadium is mainly vanadium titano-magnetite and Rock coal containing alum.Vanadium titano-magnetite is through blast furnace process
Enter molten iron afterwards, then by bessemerizing to obtain vanadium slag.Vanadium in Vanadium Residue hercynite is mutually the main phase of object containing vanadium.Vanadium product in bone coal
The low and complicated occurrence state in position, in order to realize the enrichment and separation of vanadium in bone coal, Chinese patent CN106011456A and
CN107641723A is using bone coal as initial feed, and di-iron trioxide is as additive, and under reducing atmosphere, temperature is 1200 DEG C of roastings
It burns, obtaining after magnetic separation has vanadium iron spinel-type concentrate containing vanadium.In conclusion either vanadium titano-magnetite, or contain vanadium
Bone coal can convert vanadium to vanadium iron spinelle object phase.Therefore, from vanadium iron spinel-type containing efficient green vanadium extraction in vanadium mineral
There is extremely important meaning.
Currently, the prevailing technology from vanadium iron spinel-type containing vanadium extraction in vanadium mineral is sodium roasting, it is directly logical after roasting
Water logging is crossed to obtain containing vanadium leachate.But product of roasting sodium metavanadate leads to material because forming a large amount of liquid phases since fusing point is low
Sintering, to reduce the leaching rate of vanadium, and can generate HCl, Cl in roasting process2Equal pernicious gases, pollute environment.In order to
Material sintering and noxious gas emission are avoided, metallargist proposes a kind of method of vanadium slag calcification baking, by lime and vanadium
After slag mixing, direct high-temperature roasting obtains by sulfuric acid leaching after roasting and contains vanadium leachate.But maturing temperature is higher, most
Up to 950 DEG C or so, consume energy larger, equipment loss is big.
The disadvantages of generating pernicious gas and high energy consumption high pollution in order to avoid roasting technique, metallurgists use acidleach
Or alkali soaking technology carries out vanadium extraction from mineral containing vanadium resource, Xu Mengchun et al. carries out experimental study to tailings in vanadium extraction leaching behavior
(experimental study [D] the Northeastern University of Xu Mengchun tailings in vanadium extraction leaching behavior, 2012.), the result shows that, tailings in vanadium extraction difference
Using alkali extract technology and oxalic acid extract technology, the leaching effect of similar vanadium is obtained.Under the conditions of alkali extract technology, with alkali
The increasing of concentration and liquid-solid ratio, the leaching of vanadium take the lead in increase after decline, as the temperature rises with the extension of extraction time, vanadium
Leaching rate gradually rises.In oxalic acid extract technology, with the increase of oxalic acid additional amount and the extension of extraction time, the leaching of vanadium
Rate gradually rises.But either alkali soaking technology or oxalic acid extract technology, the rate of recovery of vanadium is too low, and up to 66% is left
It is right；The two technique extraction temperature is higher, and at 150 DEG C or more, therefore it is larger to consume energy, and needs high-tension apparatus, equipment investment is higher.This
Outside, leachate impurity element is more, leaches in residue there are also the vanadium not being leached largely and chromium, cannot arbitrarily discharge, soaks
Tailings processing is difficult out.
Contain vanadium mineral by electrochemical decomposition vanadium iron spinelle, is a kind of cleaning, efficient vanadium extracting new method.Chinese patent
A kind of method that CN102134640A proposes electrocatalytic oxidation leaching Converter Vanadium-bearing Slag, by Converter Vanadium-bearing Slag and MnSO4、H2SO4It is tuned into mine
Slurry leach without diaphragm electrocatalytic oxidation.But the rate of recovery of this method vanadium is low, and has additive to be added to electrolyte solution
It is interior, difficulty is caused to the separation of subsequent vanadium.
Chinese patent CN103060843 and CN103421950A propose a kind of molten using potassium hydroxide solution as electrolyte
Liquid, the synchronous method for extracting vanadium chromium of electrochemical decomposition vanadium slag.Mixed ingredients are made in vanadium slag and potassium hydroxide aqueous solution Hybrid Heating
Slurry, is then added in normal pressure electrolytic cell, oxidizing gas is passed through into solution, is electrolysed to obtain reaction slurry, obtains and contain vanadium
Leachate.But the method, there are still many deficiencies, electrolyte solution uses potassium hydroxide as electrolyte, improves and is produced into
This, and concentration of potassium hydroxide is larger, and corrosivity is stronger；Before cell reaction, need mixed to vanadium slag and potassium hydroxide aqueous solution
Heating is closed, to increase energy consumption；It in electrolytic process, needs continuously to be passed through oxidizing gas into reaction system, increases
Production cost and bring security risk.
