The results of a study to evaluate promising alternatives to the Hot Water Extraction Process for extraction of bitumen from mined oil sands are reviewed and reassessed in light of recent developments in bitumen extraction technology. It is found that the Syncrude developments increase bitumen recovery and energy efficiency and reduce production costs to levels comparable to other promising aqueous extraction processes. Concerns with tailings accumulation of the process remain unresolved. These accumulations represent major environmental and resource recovery concerns. A high priority should be placed on developing a suitable commercial process to overcome these concerns.
