Separation and purification of tantalum from plumbomicrolite of amazonite deposit in Kola Peninsula by acid leaching and solvent extraction

A plumbomicrolite concentrate (PMC) was decomposed with the mixture of HF and H2SO4, HF and HCl, HF and HNO3 acids. Optimal conditions ensuring high recovery of tantalum and niobium (99%) into solution, and radionuclides into insoluble residue were determined. Fluoride-sulfuric acid and fluoride-nit...
