Systematic study for thermal decomposition of monazite to remove phosphate as a valuable product using Na2CO3 and NaOH roasting processes to validate the TG/DTA studies is reported here. Monazite in 1:1 wt. ratio with Na2CO3 and NaOH requires a temperature of 900 ℃ and 400 ℃, respectively, for 120 min in order to achieve complete conversion of rare earth phosphate into its oxides. The roasted mass was washed, dried and leached in 6 M HCl for 2 h, pulp density 30 g/L at 80 ℃ which results in >90% REMs recovery. Leach liquor generated will be further processed by solvent extraction and precipitation processes.
