Abstract: Processes for conditioning a dry tailings material from a non-aqueous extraction (NAE) process for extracting bitumen from oil sands ore are described. The process can include contacting a main stream of the dry tailings material with a re-wetted tailings seed stream to produce a combined tailings material, and subjecting the combined tailings material to re-wetting to produce a re-wetted tailings material. The re-wetting can include adding a wetting agent to the combined tailings material, and imparting mixing to the combined tailings material. Contacting the main stream of the dry tailings material with the re-wetted tailings seed stream can include recycling a portion of the re-wetted tailings material to the main stream of the dry tailings material as the re-wetted tailings seed stream to produce the combined tailings material, or subjecting a sub-stream of the dry tailings material to sub-stream re-wetting to produce the re-wetted tailings seed stream.
