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.

Claim (Index 4):
A method of separating solid materials from a suspension of produced water comprising solid materials and water from an oil and gas well, the method comprising: dispersing a polymer flocculent into the suspension such that the polymer flocculent interacts with the solid materials, the polymer flocculent comprising an anionic organic polymer with a molecular weight in the range from 30,000-50,000 daltons.
