Abstract
A kind of novel method of extracting Vanadium Pentoxide in FLAKES from contain vanadium solution the present invention relates to the extraction of vanadium.Employing contain vanadium solution and alkaline leacheate be separated by by subtracting property anion exchange resin bed a little less than the wide aperture, collection contains vanadium concentration up to 60-100 grams per liters, it is clean to have environment, simple to operate, compare with 717 resins, loading capacity can improve 3-5 times, and reagent reduces 50%, and vanadium recovery improves 5-8 percentage points.Adapt to domestic each large, medium and small type vanadium smelter, it is convenient to implement.
Description
A kind of novel method of extracting Vanadium Pentoxide in FLAKES from contain vanadium solution the present invention relates to the extraction of vanadium.Be adapted to domestic vanadium smelter.
At present, the domestic Vanadium Pentoxide in FLAKES that extracts from contain vanadium solution must make vanadium change liquid phase over to from solid phase, realizes that vanadium separates with most impurity, as water-leach liquor or acid (alkali) leach liquor.Also useful strongly basic anion exchange resin (717) extracts Vanadium Pentoxide in FLAKES, and still, the loading capacity of vanadium extraction is low, and reagent consumption is big, and cost is higher, the product percent of pass instability.
The object of the present invention is to provide a kind of wide aperture weak basic anion exchange resin, reach rate of recovery height, constant product quality, cost is low.
Above-mentioned purpose can reach like this: the vanadium solution (water-leach liquor, acid (alkali) leach liquor) that contains of different sources is adjusted acidity with the conventional chemical method, and PH=0～9, and allow the molten wide aperture weak basic anion exchange resin of flowing through and having set of liquid.This resin only adsorbs vanadium, reaches vanadium and separate impurities, at this moment, we again alkaline leacheate by being adsorbed with the resin of vanadium, vanadium drip washing is got off, at this moment vanadium has separated again with resin.And the vanadium in the leacheate can be collected 60～100 grams per liters.
The present invention and branch know that technology compares, and have various advantages:
1, compare with the extraction process of liquid-liquid, it is clean to have operating environment, and simple to operate, safety, product are stable.
2, compare with 717 resin technologies, have the high 3-5 of loading capacity doubly, amount of reagent reduces 50%, constant product quality, the high 5-8 of the rate of recovery percentage point.
Accompanying drawing is a technical process circle of the present invention
Best enforcement of the present invention is: shown in the accompanying drawing, 1, different sources contain vanadium solution (water-leach liquor, acid (alkali) leach liquor), use hydrochloric acid, sulfuric acid and liquid caustic soda are adjusted solution acidity, generally keep PH between 0～9, the best is got PH between 3-6, if when throw out occurring, preferably filters clean.
2, the preceding liquid of exchange that mixes up acidity is directly by being equipped with the resin bed of wide aperture anionite-exchange resin, and vanadium optionally is adsorbed on the resin, and other impurity element has been realized the purpose of vanadium and other separation of foreign elements with outside the solution spouting bed.
3, make eluent with the strong liquid of alkalescence, preferably get 0.5～2N sodium hydroxide solution, vanadium drip washing from resin is got off to change over to obtain the solution containing vanadium concentration up to 60～100 grams per liter Vanadium Pentoxide in FLAKES leacheates directly by adsorbing the resin bed of vanadium.
4, ammonium chloride is joined contain in the vanadium leacheate, vanadium generates the ammonium meta-vanadate precipitation, obtains the ammonium meta-vanadate solid after separating after filtration, and waste liquid flows into waste water purification tank.
5, the ammonium meta-vanadate solid is delivered in the revolving drum, gets 99 grades of Vanadium Pentoxide in FLAKESs of GB 550 ℃ of following calcinations.
6, the waste liquid in the above-mentioned flow process all flows in the treating pond, adds the processing of heavyization of lime, reaches standards for industrial water usage, returns the industrial system recycle.
Of the present invention fourth, fifth, six all belong to the method that vanadium factory generally adopts, and transform easily.
