Abstract

The basic technological scheme of scandium extraction refining from mixed chloride-nitric solutions was proposed. It was shown, that purification of scandium from zirconium, thorium and iron admixtures reached more than a hundred times during the extraction process using 75 % three-isoamilphosphat in dodecane on four extraction steps
