Description
Technical field
The invention belongs to the purification enrichment technical field that contains the vanadium aqueous solution.Relate in particular to a kind of method for purifying and enriching of low-concentration vanadium-containing water solution.
Background technology
It is relatively low that the overwhelming majority contains the vanadium grade of vanadium raw materials, the main both at home and abroad wet method process for extracting vanadium that adopts.Because various places contain the different of vanadium raw materials and integrated artistic requirement, water logging goes out at the wet method process for extracting vanadium and still occupies an important position.
Because to contain vanadium raw materials vanadium grade lower usually, to contain vanadium solution vanadium concentration also lower so leach gained, and foreign matter content such as other metal ions is higher in the solution, as if directly carrying out precipitation operation, gained V
2O
5Product purity have only 86% usually (" non-ferrous extractive metallurgy handbook editorial board. " and under the rare refractory metal of non-ferrous extractive metallurgy handbook, Beijing: metallurgical industry press, 1999:335), can not satisfy application requiring far away.Therefore, production high purity vanadium product must carry out purification enrichment to the low-concentration vanadium-containing infusion solution to be handled.
For a long time, the purification enrichment that contains vanadium solution both at home and abroad mainly contains extraction and ion-exchange dual mode.The extraction process operating speed is fast, easy and simple to handle, but the extraction process route is long, extraction conditions harshness, fluctuation of service.Comparatively speaking, ion exchange process (Liu Guoan, Li Liaosha, Yu Liang. contain useless admittedly vanadium extraction technology of vanadium and prospect. metal mine, 2003 (10): 63) selectivity is strong, raw materials consumption is few, environmental pollution is little, reusable edible.
During wet method vanadium extraction is both at home and abroad used at present, contain the employed ion exchange resin of vanadium infusion based on strongly basic anion exchange resin.Containing the vanadium aqueous solution can realize purification enrichment by using strongly basic anion exchange resin, but in operation process, contains also enrichments relatively of impurity such as Si, P in the vanadium aqueous solution, As, Mn, Al, influences the quality product of precipitation operation, causes precipitation rate instability.Removal of impurities (Xu Hongbo is precipitated to containing before the vanadium aqueous solution then adopts ion-exchange in domestic advanced minority enterprise and scientific research institutions, Luo Yunli, the leaves of pulse plants is good for Kui. vanadium leachate dephosphorization research, the Sichuan non-ferrous metal, 2002 (3): 29), but this mode medicament (being generally calcium chloride or calcium oxide) consumption is big, the vanadium loss is big, and produce a large amount of mud and can not handle on time, an operation is in time sent qualified liquid backward, the continuity that influence is produced.The follow-up precipitation of the rich vanadium liquid of gained is still unstable behind the purification and impurity removal, particularly for the water logging process for extracting vanadium that adopts partial material and water circulation comprehensive to utilize, because impurity is just more obvious to the unsettled influence of precipitation also by the enrichment that circulates simultaneously.
Summary of the invention
The purpose of this invention is to provide a kind of technology simple, save time, the method for purifying and enriching of the scavenging agent consumption is few, the rate of recovery of good purification, vanadium is high low-concentration vanadium-containing water solution.
To achieve these goals, the technical solution used in the present invention is: earlier at V
