Mineralogy and Beneficiation of Vein-Type Apatite Rare ...

1. Introduction. Globally, rare earth elements (REEs) play an essential role in high technologies. Currently, about 95% of the world's rare earth (RE) resources and REO production occur in bastnaesite, monazite, and xenotime (Miyawaki and Nakai, 1996, Gupta and Krishnamurth, 2005).However, because the demands for RE materials worldwide are increasing (US Geological …

Extraction Technology - National Space Society

"The mineralogical barrier" described by Skinner (see fig. 34) refers to the point at which the easily processed minerals, such as sulfides, are so rare that mineral beneficiation techniques cannot be applied economically. At this level, the increased energy required to extract trace metals from silicates must be expended.
