Dry, stackable tailings and methods for producing the same
Abstract:
Methods for preparing solvent-dry, stackable tailings. The methods may include a primary leaching or extraction process that separates most of the bitumen from a material comprising bitumen and produces first solvent-wet tailings. The first solvent-wet tailings are washed with a second solvent that removes the first solvent from the tailings. Second solvent remaining in the tailings is removed to thereby produce solvent-dry, stackable tailings.
