  • Multiple output stream particle beneficiation and chemical processing
    Patent number: 9528700
    Abstract: A reactor (110) serves to combust residual carbon in fine particulate matter, remove a contaminant from fine particulate matter, or change the composition of fine particulate matter. The reactor output is processed by particle collection devices (115, 125, 140, 155, 175) and heat exchangers (135, 150, 165) to provide particle outputs (118, 124, 131, 144, 159) of different sizes. A contaminant, such as carbon or a metal, is combusted, vaporized, volatized, broken down, or substantially appears on one particle output (144) so that another particle output and the exhaust gas (142) are substantially contaminant-free. Different outputs can also be selectively mixed, as desired, to product a combined output (171). Fly ash and silica fume can be processed separately or together to reduce the amount of unburned carbon in both. Metals can also be removed from the fine particulate matter. Kaolin can also be processed to produce metakaolin.
    Type: Grant
