Abstract
(not available in English)
This study was conducted with different experimental conditions such as acids, temperatures, and reaction times for investigating leaching behavior for rare earth element (REE) leaching. In this study, phosphogypsum (PG) sample was obtained from a real PG plant in Florida and sample characteraziton was evaluated for REE, P2O5, 238U, and 232Th contents. Then preliminary leaching experiments were conducted as kinetic experiments with 9 different experimental conditions. These leaching tests showed that leaching yield was not so high. PG sample's leaching was so difficult, complex to get into solution also the REE concentration was small.
