## Abstract Important process development aspects leading to more efficient bitumen recovery from diluentβconditioned oil sands by waterβbased methods are discussed. Bitumen viscosity of 0.5β2 PaΒ·s is required at the processing temperature and can be reduced to this level by bitumen dilution with a
The temperature dependence of, first, the yield of bitumen extracted from oil sands and, second, of the coextracted solid particles in the bitumen was studied. Centrifugal extractions were performed in an argon (inert) atmosphere at temperatures ranging from 30Β°C to 150Β°C. The co-extracted solid par
