Depth-Resolved Oxidation, Flotation Recovery and Coke Strength in Blends
A paper in energy and fuel science from the School of Settled Matters cores a 14 ha fine-coal tailings impoundment at a washery closed for more than two decades and tests 18 depth composites. Reflectance is uniform with depth, but coal above the mean water table at 1.6 m has lost most or all of its fluidity, while the saturated body below it floats to 9.8% ash at 73% combustible recovery and replaces up to 10% of a pilot-oven blend for a loss of 1.1 points of coke strength after reaction.
