RECOVERY OF THE TOTAL OXIDES OF THE RARE EARTHS FROM MONAZITE IN QUANG NAM
Abstract
The application of the normal hydrothermal and microwave hydrothermalprocess to recover the total oxides of the rare earths from monazite in Quang Nam by acidsHCl, HNO3, H2SO4 and alkali NaOH have been studied.Research results show that the best conditions to obtain the total rare earth oxide in QuangNam and with the highest performance microwave hydrothermal metallurgy ore monazitein Quang Nam particle size < 0,076mm in the rate of 12M H2SO4 /ore is 5:1 (ml/g) in 60minutes in the microwave power 450WReferences
