Abstract
The invention relates to a method for removing vanadium from a gallium-enriched solution in resin-absorbed seed precipitation mother liquor, which is characterized in that the weight of lime added to the gallium-enriched solution in the vanadium removing process is 27-37g/l in terms of available calcium. The method has good effect of removing vanadium, ensures that the concentration of vanadium can be lower than 0.02g/l after removing vanadium, effectively reduces the problem of burning the polar plates in the electrolytic process and meets the requirement for normal operation of production.
Description
Technical field
The present invention relates to the vanadium removal method of gallium enrichment solution in a kind of resin absorption seed precipitation solution.
Background technology
At present, the effective ways that extract gallium from seed precipitation solution are to adsorb gallium with resin from seed precipitation solution, come out with desorption liquid desorption from resin again, form the gallium enrichment solution, during separating, enrichment solution also includes heavy metals such as vanadium and lead, copper, therefore next lysate is removed vanadium except that heavy, form electrolytic solution, obtain gallium by electrolysis process at last.Vanadium removal method wherein is that to remove the impurity vanadium be to utilize CaO+V with adding lime in the gallium lysate

5Principle, add that a certain amount of lime finishes.
At present, in the production practice, the lime addition in the concentration of Vanadium Pentoxide in FLAKES in the lysate with 0.3g/l, with the lime level that contains effective calcium of 75% is radix, but it removes the vanadium poor effect, usually do not reach except that vanadium requirement (V≤0.02 g/l), and the regular burning pole plate of electrolysis link, the rate of recovery is lower.
Summary of the invention
Purpose of the present invention is exactly the deficiency that exists at above-mentioned prior art, provides that a kind of to remove vanadium effective, and can effectively reduce the vanadium removal method of gallium enrichment solution in the resin absorption seed precipitation solution that electrolytic process burns the pole plate problem.
The objective of the invention is to be achieved through the following technical solutions.
The vanadium removal method of gallium enrichment solution in a kind of resin absorption seed precipitation solution is characterized in that the amount of lime that its vanadium removal process adds counts 20～28g/l with effective calcium in the gallium enrichment solution.
The vanadium removal method of gallium enrichment solution in a kind of resin absorption seed precipitation solution of the present invention, it is effective to remove vanadium, removes that the concentration of vanadium can reach below the 0.02g/l behind the vanadium, effectively reduces electrolytic process and burns the pole plate problem, has satisfied and has produced normal operation needs.

From testing data, when adding lime concentration (the active calcium ion content is 75%), can satisfy production requirement basically, slightly fluctuation at 30g/l.Reach 35g/l at the adding lime powder, basic ripple disable removes vanadium concentration and all reaches basically below the 0.02g/l, satisfies and produces normally operation.
With this, we have groped out one and have removed the vanadium standard in production practice, promptly add lime by the standard of 20～28g/l, have well satisfied actual needs.
During operation, measure the volume V of the lysate that will remove vanadium, then according to formula V(
Lysate) * (20～28) ÷ n
(content of the effective calcium of lime), calculate the weight of the lime that will add, take by weighing lime, to add in the lysate, temperature raising to 100 ℃ reaction 2 hours in this process, is stirred always, guarantees to mix sufficient reacting, by filtering operation, vanadium is removed at last.
