Abstract
Methods for preparing metakaolin-enhanced industrial minerals. Mixing and heating kaolinite clay with an industrial mineral, such as activated carbon, that is between 750° F. and 1400° F. results in a metakaolin/activated carbon complex that provides good mercury sorbent qualities while producing a fly ash (after use as a sorbent in emissions applications) that has a lower foaming index.

A method of producing metakaolin, comprising the step of heating kaolinite clay as an initial co-product with one or more other industrial minerals during a heat treatment process at a temperature and for a time sufficient to create metakaolin.
A method of producing metakaolin, comprising the step of heating kaolinite clay with a hot industrial mineral, wherein said kaolinite clay is added to the hot industrial mineral after said industrial mineral has been heated to a temperature of between 750° F. to 1400° F. and discharged from a furnace or calciner, and the kaolinite clay is heated soley using the heat from the hot industrial mineral for a time sufficient to create metakaolin.
A method of sorbing a contaminant in a flue gas, comprising introducing a metakaolin-doped activated carbon into a flue gas such that fly ash containing said metakaolin-enhanced activated carbon is produced.
