THE HYDROTHERMAL RECRYSTALLIZATION OF METAMICT ALLANITE-(Ce)

open access: yesThe Canadian Mineralogist, 2010
Samples of metamict allanite-(Ce) originating from granite pegmatites were recrystallized by heating in air and under hydrothermal conditions. Recrystallization in air resulted in partial recovery of the crystal structure at 650°C. Heating at higher temperatures resulted in decomposition of the allanite structure to a multiphase assemblage containing ...

Physicochemical aspects of allanite flotation

Journal of Rare Earths, 2014
Abstract This paper investigated the physicochemical properties of allanite, a RE-silicate, by measuring zeta potential in the absence and presence of three different flotation collectors (benzohydroxamic acid, sodium oleate and dodecylamine). This data was then verified by microflotation experiments and with bubble-particle attachment pictures.
