Abstract:
A method is provided for recovering scandium values from scandium-bearing ores. The method includes providing a scandium-bearing ore; subjecting the scandium-bearing ore to atmospheric pressure acid leaching with sulfuric acid, thereby producing a first, scandium-bearing solution containing ferric (Fe 3+ ) ions; subjecting the first solution to hydrothermal processing, thereby precipitating from the first solution a material selected from the group consisting of hematite and basic iron sulfates and generating a second, scandium-bearing solution; and recovering scandium values from the second solution.

Claim (Index 14):
A method for recovering scandium values from scandium-bearing ores, comprising:\n providing a scandium-bearing ore; subjecting the scandium-bearing ore to atmospheric pressure acid leaching with sulfuric acid, thereby producing a first, scandium-bearing solution containing ferric (Fe 3+ ) ions; and subjecting the first solution to acid retardation, thus obtaining second and third solutions, wherein the second solution has higher concentrations of Sc and ferric ions than the third solution, and wherein the third solution has a higher concentration of acid than the second solution.
