A two-step phosphorus–sulfur wet-process phosphoric acid route enabling simultaneous rare earth leaching and co-production of high-whiteness hemihydrate gypsum whiskers

The conventional wet-process phosphoric acid production results in most associated rare earth elements (REEs) being retained in phosphogypsum, rendering their recovery uneconomical. To address this challenge, this study proposes a novel two-step phosphorus-sulfur wet process. In...
