(763h) Froth Flotation Enrichment of Rare Earth Elements (REEs) from Different Feedstocks
AIChE Annual Meeting
Thursday, November 2, 2017 - 5:28pm to 5:45pm
The effectiveness of surfactants, i.e., frother, depressant, and collector, can strongly influence the flotation process, including the enrichment of rare earth elements (REEs) from coal, coal by-products or fly ashes. The properties of particle size, temperature, and pH will also affect REE enrichment. Here, we report the performance of different chemicals/process parameters for the froth flotation of different feeds in the mechanic agitated flotation cell. Different types of frothers and collectors were studied at varying flotation conditions for REE enrichment. The discussion will focus on the performance of these surfactants and the REE enrichment efficiency at these different conditions.
