B -- BENCH-SCALE TESTING OF MECHANICAL AND TALL COLUMN FLOTATION SOIL SEPARATION SYSTEMS SOL DE-RP24-950H20007 due 052295. Contact Point, Michael J. Kepler, Contracting Officer, (513) 865-3849. The U.S. Department of Energy intends to award a contract to the University of Nevada, Reno, to conduct bench-scale testing of innovative applications of proven flotation technologies from the minining industry to remove uranium from soil. Bench-scale testing of Mechanical Flotation and Column Flotation Separation Systems will be conducted in order to confirm the results of previous testing performed on Fernald Environmental Management Project soils, to optimize operating parameters, establish operating conditions, and to optimize the process strategies for a sequential flotation process to incorporate a carrier to enhanced mechanical flotation with the tall column. The University of Nevada has been selected as the sole source for this effort because of their unique qualifications regarding this area of research. As a result of the University of Nevada's work on the Heavy Metals Contaminated Soils Project, university personnel have an in-depth knowledge of, and experience with, advanced mineral processing technologies associated with radioactive contaminated soils and possesses a unique combination of skills including experienced mineral processing engineers familiar with the latest developments of their industry, qualified radiation safety professionals, and hazardous materials experts. Moreover, the University of Nevada possesses a new, and state of the art laboratory and testing facility to conduct demonstration tests, analyze the results, and perform technology evaluations. This laboratory is a DOE supported Soil Washing Laboratory and is unique in the sense that it provides controlled environment as often as needed to carry out the soil decontamination research. The University of Nevada has a current license to possess radioactive contaminated soils and also has been designated as a DOE support facility. The solicitation will be issued approximately 20 April 1995. See Note 22. (087)
