Abstract
A method for processing a froth treatment tailings separated from a bitumen froth produced in a process for recovering bitumen from oil sand ore, includes subjecting the froth treatment tailings to a first solvent extraction process to produce a first extract including bitumen, and a first raffinate, subjecting the first raffinate to a separation process to produce a fine mineral material fraction including fine solid mineral material having a particle size less than 44 microns and a coarse mineral material fraction including a coarse mineral material having a particle size equal to or greater than 44 microns, subjecting the coarse mineral material fraction to a froth flotation process to produce a heavy mineral concentrate and a coarse mineral material tailings, and subjecting the heavy mineral concentrate to a second solvent extraction process to produce a second extract including bitumen and a second raffinate including a debitumenized heavy mineral concentrate.
