Abstract
A process for preparing a granular ceramic mixture includes the steps of: (a) contacting fluid bed combustion fly ash with an acidic aqueous solution to obtain acidic fluid bed combustion fly ash slurry; (b) removing excess acid from the slurry obtained in step (a) to obtain solid acid treated fluid bed combustion fly ash; and (c) contacting together: (i) the solid acid treated fluid bed combustion fly ash obtained in step (b); (ii) clay; (iii) optionally, feldspar; and (iv) optionally, other ingredients.
