ABSTRACT:
In a hot water extraction process for removing bitumen from oil sands, the efficiency is improved by filtering the wet tailings to recover hot water, bitumen and diluent which are returned and recovered in the process. Dry tailings are also produced which can be disposed of in a manner which permits reconservation of the mined out area and which eliminates environmental pollution impact on surrounding water bodies and land bodies.
