Abstract: Separation methods for producing an extract and a raffinate from a solvent extraction feed material, wherein the feed material is derived from a process for recovering bitumen from oil sands. The methods may include producing an intra-stage recycle component from an overflow zone of a solvent extraction stage and recycling the intra-stage recycle component to the solvent extraction stage, and/or the methods may include providing an underflow component withdrawal rate for a solvent extraction stage other than a final solvent extraction stage which is greater than an underflow component withdrawal rate for the final solvent extraction stage.

Abstract: A method for processing a heavy mineral concentrate obtained from froth treatment tailings to produce a zirconium concentrated product, including subjecting the heavy mineral concentrate to froth flotation, subjecting a flotation product to initial gravity separation, subjecting an initial gravity separation product to primary dry separation, subjecting a primary dry separation product to finishing gravity separation, and subjecting a finishing gravity separation product to finishing dry separation to produce a finishing dry separation product as the zirconium concentrated product.

Abstract: A method for recovering a tailings bitumen from a froth treatment tailings, including providing a first feed material which is derived from the froth treatment tailings, conditioning the first feed material in order to produce a conditioned first feed material, providing a second feed material which is derived from the conditioned first feed material, and subjecting the second feed material to solvent extraction in order to produce an extract containing an amount of the tailings bitumen. The method may further include dewatering the conditioned first feed material in order to produce the second feed material and may further include clarifying the extract to produce a clarified extract containing an amount of the tailings bitumen.
