Comparative Leaching Behavior and Radiological Assessment of Igneous and Sedimentary Ore-Derived Phosphogypsum from Five Major European Deposits
Abstract Phosphogypsum (PG), a major by-product of phosphate fertilizer production, is an underutilized secondary source of rare-earth elements (REEs) and naturally occurring radioactive materials. This study presents a comparative assessment of REE leaching behavior and radionuclide partitioning in PG from major Europ...
