Method for extracting and separating high-purity yttrium from naphthenic acids in high stability

The invention relates to a method for extracting and separating high-purity yttrium from naphthenic acids in high stability, which still can guarantee a suitable phase ratio in a mixing chamber to guarantee the mixing chamber to be a sticky state when oil and water phases are extremely large or have severe fluctuation during the process that the high-purity yttrium is extracted and separated form the naphthenic acids, thereby enabling mixing phases to be rapidly clarified and separated in a clarifying chamber. The method for exacting and separating high-purity yttrium from naphthenic acids in high stability is simple in process, can rapidly and steadily adjust the phase radio of the naphthenic acids for extracting and separating the high-purity yttrium in the mixing chamber by adopting simple operation steps, rapidly builds a mixing chamber sticky system again, guarantees the clarifying chamber to normally separate phases, is simple in operation and excellent in stability, reduces technical requirements to operators, and is beneficial for stable production of enterprises.
