Recovery of thorium from uranium solutions

2017-1-12 · At Elliot Lake, Ontario, thorium has been recovered from uranium ore leach solutions, after removal of the uranium by ion exchange resin, since 1959. A solvent extraction process is used, and the thorium is recovered as thorium sulfate by stripping the loaded solvent with moderately strong sulfuric acid. The product, recovered by filtration, is directly shippable, but can also be easily
