The present invention is directed to a method comprising contacting an oil sand with a suitable solvent to generate a solvated oil sand slurry; separating solvent-diluted bitumen from the solvated oil sand slurry to generate (a) a solvent-diluted bitumen and (b) a slurry with increased solids concentration; and filtering the slurry with increased solids concentration. The method of the present invention may be used to produce a low ash bitumen product and dry tailings from oil sands.

Closed loop solvent extraction process for oil sands

A process for sequestration of carbon dioxide comprising the following steps: (a) dispersing solid waste material comprising calcium oxide and a calcium-comprising mixed oxide in water to dissolve at least part of the calcium oxide and to form calcium oxide-depleted solid waste material in a calcium hydroxide solution; (b) separating the calcium hydroxide solution from the calcium oxide-depleted solid waste material; (c) converting the calcium hydroxide in the separated calcium hydroxide solution in precipitated calcium carbonate; and (d) contacting an aqueous slurry of the calcium oxide-depleted solid waste material with carbon dioxide for mineral carbonation of the carbon dioxide to form carbonated solid waste material.
