Abstract:
Methods and systems for treating oil sands tailings streams using multiple dosages of lime are disclosed herein. In some embodiments, the method comprises providing a tailings stream including 3-40% solids by total weight, combining the tailings stream with a first dosage of lime to produce a first mixture having a pH of less than 12.0, and then combining the first mixture with a polymer to produce a second mixture. In some embodiments, the method can further include combining the second mixture with a second dosage of lime to produce a third mixture having a pH greater than 12.0, and dewatering the third mixture in a centrifuge unit and/or a pressure filtration unit to produce a product stream having 55% or more solids by weight.

Claim (Index 8):
The method of  claim 7  wherein the tailings stream includes bicarbonates, the method further comprising:\n recycling at least a portion of the second stream to be mixed with the tailings stream prior to the addition of the first dosage, wherein recycling the second stream increases the pH of the tailings stream and reduces the bicarbonates of the tailings stream.
