Abstract

A process for drying mature fine tailings is provided. A low molecular weight anionic organic polymer is contacted with a tailings stream to flocculate mature fine tailings and enhance dewatering. The tailings stream can contain, for example, water, sand, silt and fines clays produced from a bitumen extraction process for oil sands ore. The process can also involve rigidification of the suspension.
