Processes are described for extracting hydrocarbon from a mineable deposit, such as bitumen from oil sands. The integration of solvent-based extraction processes with aqueous extraction processes is described. In one embodiment, water is removed from an aqueous bituminous feed that is then directed into a solvent-based extraction process. In another embodiment, a stream produced through solvent extraction is directed into an water-based extraction process. In the solvent-based extraction processes, agglomeration of fines may be employed to simplify subsequent solid-liquid separation. The process permits recovery of hydrocarbon that has conventionally may have been too difficult to recover from oil sands processing, and thus has previously been lost. Advantageously, a fungible product can be formed more efficiently according to certain integrated processes described herein.
