Abstract
A system and method for treating tailings from a bitumen froth treatment process such as TSRU tailings. The tailings are dewatered and then combusted to convert kaolin in the tailings into metakaolin. Calcined fines and heavy minerals may be recovered from the combustion products, namely from the flue gas and bottom ash.
