Abstract

Fresh hot tailings, from the hot water extraction process for removing bitumen from oil sand, are treated to remove fine clay solids ("fines") in the suspension. Ca(OH)2 lime is added to the suspension to reduce the stability of the clay-water colloidal structure. Then CO2 is injected to react with excess Ca++ and form water-insoluble CaCO3. The CaCO3 adsorbs fines and sediments them.
