Abstract:
The present invention relates to a method of dewatering an aqueous mineral suspension comprising introducing into the suspension a flocculating system comprising a mixture of polyethylene oxide polymers, in particular a mixture of one or more high molecular weight polyethylene oxide polymer and one or more ultra high molecular weight polyethylene oxide polymer. Said mixture of polyethylene oxide polymers is useful for the treatment of suspensions of particulate material, especially waste mineral slurries. The invention is particularly suitable for the treatment of tailings and other waste material resulting from mineral processing, in particular, the processing of oil sands tailings.

Claim (Index 1):
A method of dewatering an aqueous suspension of particulate material comprising the steps of:\n a) adding to the aqueous suspension a mixture of polyethylene oxide polymers comprising\n (i) one or more high molecular weight polyethylene oxide polymer (PEO) having an average molecular weight from 100,000 to 5,000,000 g/mol and \n (ii) one or more ultra high molecular weight polyethylene oxide polymer (PEO) having an average molecular weight from 4,000,000 to 10,000,000 g/mol, \n wherein the average molecular weight of the ultra high molecular weight PEO is at least 1.5 times greater than the average molecular weight of the high molecular weight PEO; \n b) allowing the suspension to flocculate; and c) dewatering the suspension.
