Abstract

This invention involves the separation of clay-contaminated bitumen from sand with a solvent. The bitumen is dissolved with an organic solvent such as condensate from a natural gas well.
The clay is separated from the dissolved bitumen and the solvent is recovered and recycled. The sand is washed with water containing a carefully selected, nonanionic surface active agent to remove residual bitumen and solvent. Prior removal of the clay precludes it from unduly contaminating the water.
