Characterization and Beneficiation of Bitumen-Free Domestic Tar Sands

摘要

The Bureau of Mines conducted a study to determine if residues from fractional distillation represent a potential source of mineral values. To develop this information, pilot plant tar sand residues or toluene-cleaned tar sands from 23 deposits were examined. The nature of the residues was determined by standard mineralogical methods and the chemical compositions were determined by X-ray and inductively coupled plasma spectroscopy.
