The extraction of metals from coal ash was investigated as part of a Bureau of Mines program to convert waste materials from a disposal problem to potential secondary resources. The objectives of this study were to produce a more environmentally acceptable waste and offset waste disposal costs with recovered metal values. The research was conducted in two steps: determination of parameters affecting extraction of aluminum from coal ash, and development of extraction-recovery procedures.
