Workbook providing washability data and REE concentration data for samples collected from coal preparation plants by the University of Kentucky and analyzed by commercial laboratories. There are four streams analyzed at each facility; namely, raw coal(input), clean coal(output), coarse reject(output) and fine reject(output). Additionally, flow rates based upon plant observations are calculated and displayed beginning in cell 'AN64' on a whole sample and %Ash basis. The data consistently indicates that the highest concentrations are found in the primarily coal matter that floats at 1.6 with additional high concentration in surrounding specific gravity fractions.
