| 简介 |
Methods for treating an industrial byproduct, such as spent, granular, activated carbon, dredge spoils, or contaminated soils involve integrated steps to clean, concentrate, separate and/or otherwise collect hazardous and/or desired materials from such industrial byproducts. The cleaned, concentrated, separated, or collected materials may involve sufficient quantities to be useful to subsequent processors, raw materials, additives, and the like. Other treatment methods involve retaining the clean material stream at sufficient temperatures for sufficient time to separate and concentrate desired material for recovery therefrom, such as precious metals and rare earth elements. |
