"Earlier scandium extraction test work aimed at the recovery of scandium from Hat deposit flotation tailings demonstrated that it was possible to extract 90% of scandium to solution by employing a sulphate leach at elevated temperatures."
"Test work has now moved into the scandium recovery-optimization phase, with sequential purification for the removal of iron and aluminium followed by precipitation of scandium as a phosphate product. Although 56% (fifty six percent) of scandium was recovered to a phosphate precipitate at the first attempt, test work to improve recovery and purity is continuing, including sequential purification, precipitate washing, phosphate purity, and recovery."
