Thermodynamic model of REE leaching from monazite by hydrothermal fluids

A study determined the thermodynamic estimation of possible scales and character of LREE and MREE leaching from a model monazite by acid and alkaline fluids of chlorideuoridecarbonate composition. Results showed the possibility of LREE and MREE fractionation during monazite interaction with the high...

Zusammenfassung:	A study determined the thermodynamic estimation of possible scales and character of LREE and MREE leaching from a model monazite by acid and alkaline fluids of chlorideuoridecarbonate composition. Results showed the possibility of LREE and MREE fractionation during monazite interaction with the high-temperature uid regardless of its composition: from chloride to carbonate uids at different pHs.
