发明名称 Process for cullet beneficiation
摘要 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.

主权项 1. A process for cullet beneficiation that includes: (a) melting a mass of cullet having a heavy metal concentration of greater than 100 ppm to form a body of molten glass; (b) introducing a precipitate agent into said body, of molten glass to form a heavy metal-containing precipitate phase and liquid beneficiated glass phase within said body of molten glass, said precipitate phase having a density greater than that of said beneficiated glass phase; and then (c) separating said liquid beneficiated glass phase from said precipitate phase.
