Abstract
A method is provided for extracting scandium values from an ore feedstock. The method includes providing a feedstock of a copper ore which contains scandium values; extracting scandium values from the ore with a leaching solution, thereby obtaining a pregnant leachate; contacting the pregnant leachate with an ion exchange resin, thereby extracting scandium values from the pregnant leachate and forming a loaded extractant; stripping the scandium values from the loaded extractant with a stripping solution, thereby forming a loaded stripping solution; and precipitating the scandium values from the loaded stripping solution as a scandium-containing precipitate.
