Patrick Garcia Strickland, Laboratory Director at Frontier GeoSciences, Inc., discussed metals mobility in coal combustion residues and analytical techniques for monitoring flyash ponds. Knowledge of the ability of metals to be released from coal combustion residues is an important factor in determining the potential effects on the environment. At the end of the presentation there was a discussion of the benefits of leaching the metals out of the flyash at the plant site. Coal –fired power plants can make 30 percent hydrochloric acid and at the same time leach metals from the flyash. The metals are captured in ion exchange resins and the purified acid is sold. This will make higher chlorine coals more attractive and result in a metal free fly ash, rare metals, hydrochloric acid and gypsum as byproducts.
