ABSTRACT:
The present invention relates to a process for the recovery of hydrocarbonaceous materials from tar sand comprising subjecting a part of the tar sand to hot water extraction by mixing it with hot water, the solids and bitumen being separated and the latter treated further, and carrying out a dry distillation of another part of the tar sand which is thereby heated to temperatures above 400.degree. C, the gaseous and vaporous distillation products being cooled and condensed. This process is characterized in that at least a portion of the thermal energy required for hot water extraction originates in the dry distillation waste heat. This process is further characterized in that the solid coke-like residue recovered from the further treatment of the bitumen from hot water extraction is used as fuel in the dry distillation and in that the wet solids recovered from hot water extraction are mixed with the dry distillation residue to form a solid product which can be transported on belt conveyors.
