Evaluation, engineering and development of advanced cyclone processes. Quarterly progress report, April 1, 1995--June 30, 1995

The project goal is to develop an advanced coal beneficiation technology that can achieve high recovery of the parent coal`s calorific value, while maximizing pyritic sulfur removal. Coal cleaning is to be accomplished by physical means incorporating an advanced gravimetric process. Evaluation of different media types and their attendant systems for recovery, concentration, and regeneration is to be completed. Phase I, media evaluation, now completed,involved a paper study and a number of laboratory tests to eliminate all but the best media options. Phase II, media testing, involved detailed testing of the more promising media and separators in a closed-loop pilot facility. In the final phase, Phase III, the optimum medium, separator, and medium recovery system(s) will be tested with commercial-size equipment. steel erection for the component test stand (CTS) was completed. The foundation and flooring were readied for vessel and equipment placement. A draft component test plan was submitted. Froth flotation product and thickener underflow stream samples were obtained from the American Electronic Power Midges 31 coal preparation plant. This material is to be used in filtration studies
