- Abstract : There is currently very little information on the physico-chemical properties of rare earth element bearing minerals, or on their processing. With the increasing demand for rare earths, this is something that needs to be addressed. This paper introduces some surface chemistry analysis of fergusonite (YNbO4 ), and the bubble particle attachment. Zeta potential measurements indicate adsorption of sodium oleate and, to a lesser degree, potassium amyl xanthate onto the surface, and an increase in attachment to an air bubble is observed at pH 4·5 and 6·5. At a pH of 10·5, no attachment is observed, whether in the presence of the reagents or not. This analysis, although initial, will be used to initiate flotation tests, in order to facilitate the selective recovery of fergusonite. Two extensively characterised minerals, one hydrophilic (quartz) and one hydrophobic (galena) were also investigated as a comparison. Il y a présentement très peu d'information concernant les propriétés physico-chimiques des minéraux porteurs d'élément de terre rare, ou de leur traitement.

Cet article introduit une certaine analyse de la chimie de surface de la fergusonite (YNbO4 ) et de l'attachement de bulle-particule. Des mesures du potentiel zêta indiquent l'adsorption d'oléate de sodium et, à un degré moindre, du xanthate amyle de potassium à la surface. On observe également une augmentation de l'attachement à une bulle d'air à un pH de 4·5 et de 6·5. À un pH de 10·5, il n'y a pas d'attachement, que ce soit avec ou sans agents réactifs. Cette analyse, bien qu'initiale, sera utilisée pour initier des essais de flottation afin de faciliter la récupération sélective de la fergusonite. On a également examiné, à titre de comparaison, deux minéraux caractérisés considérablement, soit un hydrophile (quartz) et un hydrophobe (galène). … (more)
