Abstract
A process for cullet beneficiation by precipitation. A mass of cullet is melted to form a body of molten glass having a heavy metal con ration of greater than 100 ppm. A precipitate agent is introduced into the body of molten glass to form a heavy metal-containing precipitate phase and a liquid beneficiated glass phase within the body of molten glass. The precipitate phase may have a density greater than that of the liquid beneficiated glass phase. Thereafter, the liquid beneficiated glass phase is physically separated from the precipitate phase. The separated liquid beneficiated glass phase has a reduced concentration of heavy metals, as compared to the concentration of heavy metals in the body of molten glass.
