A model-based flotation control scheme is being implemented to achieve optimal performance in the handling and treatment of fine coal. The control scheme monitors flotation performance through on- line analysis of ash content. Then, based on the economic and metallurgical performance of the circuit, variables such as reagent dosage, pulp density and pulp level are adjusted using model-base control algorithms to compensate for feed variations and other process disturbances. Recent developments in sensor technology are being applied for on-line determination of slurry ash content. During the fifth quarter of this project, all work was on hold pending the final novation of the contract to Virginia Polytechnic Institute and State University
