Description

Technical Field

[0001] The utility model relates to the technical field of tantalum liquid extraction devices, in particular to a tantalum liquid low-acid extraction device. Background Art

[0002] At present, the known methods for effectively separating tantalum and niobium include fractional crystallization, chlorination distillation, ion exchange and solvent extraction; among them, solvent extraction is the most widely used. In the field of tantalum and niobium metallurgy, the mainstream method for separating tantalum and niobium is solvent extraction, which uses the process of "hydrofluoric acid leaching-MIBK extraction and separation". Specifically, the method first uses hydrofluoric acid to treat the tantalum and niobium-containing raw materials, then uses MIBK to extract the tantalum and niobium in the solution, and then uses dilute sulfuric acid to strip the niobium fluoride complex in an organic ketone phase, and then uses pure water to strip the tantalum fluoride complex.

[0003] The existing low-acid extraction device for tantalum liquid needs to stir and mix the tantalum liquid after hydrofluoric acid with the extractant during extraction. Since the extracted solutions are incompatible with each other, it is easy to cause slow mixing time during stirring, which makes the extraction time longer and affects the extraction efficiency of the tantalum liquid. Utility Model Content
