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.
