Abstract
A method for selectively removing scandium from a scandium-containing feed solution includes contacting the scandium-containing feed solution with a solvent stream in plural stages using cross current extraction, in which the solvent is loaded with at least a portion of the scandium from the feed solution, and/or ion exchange, and separating the loaded solvent from remaining scandium-containing feed solution.
