  • Publication number: 20140311951
    Abstract: A system and method for treating tailings from a bitumen froth treatment process such as TSRU tailings. The tailings are dewatered to at least 50 wt percent solids content, 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 or bottom ash or both. A trafficable deposit may be formed from the ash when mixed with tailings, such as mature fine tailings (MFT).
