Ore AAX was a very poor processing ore. The primary bitumen recovery was low at 13.0% coupled with a low primary froth bitumen content at 19.7% when no process aid was used (Table 6). Even at the highest caustic dosage (0.05 wt %), the primary recovery remained low at 26.7%, and did not appear to change with the increased caustic dosage from 0 ...
