Effect of pretreatment on synchysite-Ce (CaCe(CO3)2F) leaching

Burmaa, G., Temuujin, J. and Welham, N.J. (2007) Effect of pretreatment on synchysite-Ce (CaCe(CO3)2F) leaching. Minerals Engineering, 20 (8). pp. 807-809.

Synchysite is a rare mineral which has potential as a new source of rare earth elements. The influence of roasting temperature and time on the solubility of rare earth elements from a synchysite concentrate is examined. The maximum solubility of rare earth oxides in 57% HNO3 was 97% in a sample roasted at 700 °C for 120 min. Increasing the roasting temperature decreased solubility due to formation of cerium (IV) and calcium oxides.
