This file is a spreadsheet showing the results of multi-gravity separation testing. Each stream was separated into multiple particle size fractions, and each fraction was subjected to washability analysis at various specific gravities. Each specific gravity fraction was analyzed for ash content and a suite of 16 REEs. The REE data are presented both as concentrations of the whole coal material and of just the ash content. In addition, average REE data for what might be found in the earth’s crust is provided as a reference. A multi-gravity separator is device that is specially designed to separate fine particles on the basis of their specific gravity using centrifugal force.
