The Chemical Reaction Mechanics of Bastnaesite in Low Temperature Activation Process

Abstract:

Bastnaesite was activated at low temperature, and the results of XRD, SEM and Raman showed that the particle size of minerals increased firstly, and then decreased with increasing of temperature. The polarization of rare earths fluoride decreased in activation minerals. Using HCl leaching, the rare earths carbonate and rare earths fluoride were separated effectively, and 94.6% rare earths carbonate and only 0.07% rare earths fluoride was dissolved respectively. The results supplied a new method of bastnaesite decomposition.
