) was leached with the mixture of HF and H2SO4, HF and HNO3 acids, respectively. Optimal conditions ensuring high recovery of tantalum and niobium (up to 99%) into solution, and radionuclides into insoluble residue were determined. Fluoride-sulfuric acid and fluoride-nitric acid schemes were proposed for PMC leaching by an extractive separation of tantalum form niobium, lead and impurities, and production......
