Abstract

Calcium sulphate is added to desanded tailings derived from a hot water extraction process for recovering bitumen from oil sand. Enough calcium sulphate (100 to 200 ppm) is added to remove naphthenates and sulfonates from the aqueous phase. As a result, the settling rate of the fines in the tailings is accelerated.
