This report has been divided into three volumes. Volume I describes the MRI beneficiation work. In addition, Volume I presents the results of joint beneficiation-hydroretorting studies and provides an economic analysis of the combined beneficiation-hydroretorting approach for processing Eastern oil shales. Volume II presents detailed results of hydroretorting tests made by MYCRUDE/IGT on raw and beneficiated oil shales prepared by MRI. Volume III comprises detailed engineered design drawings and supporting data developed by the Roberts and Schafer Company, Engineers and Contractors, Salt Lake City, Utah, in support of the capital and operating costs for a conceptual beneficiation plant processing in Alabama oil shale. 26 refs., 10 figs., 23 tabs.
