摘要： 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 glycol and polyethylene oxide polymers, in particular a mixture of one or more low molecular mass polyethylene glycol with one or more high molecular mass polyethylene oxide. Said mixture of polyethylene glycol and 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.

摘要： The present invention relates to an improved bitumen recovery process from oil sands. The oil sands may be surface mined and transported to a treatment area or may be treated directly by means of an in situ process of oil sand deposits that are located too deep for strip mining. Specifically, the present invention involves the step of treating oil sands with a propylene oxide capped glycol ether described by the structure: RO—(C2H4O)n—CH2CH(CH3)OH wherein R is a linear, branched, or cyclic alkyl, phenyl, alkyl phenyl group and n is 1 to 10.

摘要： A method for forming a polyurethane coating on an industrial roller includes applying a coating that is a product of a coating forming reaction mixture, which includes a prepolymer component and a curative component, to an industrial roller. The prepolymer component includes a polycarbonate prepolymer, which is a product of a prepolymer forming reaction mixture that includes an isocyanate component and a polycarbonate polyol, and the prepolymer component is present in the coating forming reaction mixture in an amount from 30 wt % to 80 wt %, based on a total weight of the coating forming reaction mixture. The curative component includes a chlorinated aromatic diamine curative agent, and the curative component is present in the coating forming reaction mixture in an amount from 5 wt % to 20 wt %, based on the total weight of the coating forming reaction mixture. Further, the coating is cured to form a polyurethane coating layer on the industrial roller.
