Vanadium Extraction Solution and Vanadium Solvent Extraction Method

摘要

PPROBLEM TO BE SOLVED: To provide an extracting solution for vanadium and a method for solvent-extracting the vanadium with which the vanadium existing in solution can efficiently be separated and recovered by solvent-extracting. PSOLUTION: In the extracting solution for extracting the vanadium from the solution containing soda-salt of the vanadium; the extracting solution is constituted by mixing a quanternary ammonium salt extractant and dilute agent, and the dilute agent is the one containing Solvesso (R) 200 and Techreen (R) N20 and the vanadium in the solution can be extracted into the extracting solution. Then, a phase-separating term in the extracting process can be shortened, and since the phase-separating term in a reverse-extracting process and a process at thereafter can be shortened, the collecting efficiency of the vanadium can drastically be improved.
