The invention relates to improved bitumen recovery processes and systems. The process may include providing a bitumen froth feed stream, separating the stream in a froth separation unit to produce a diluted bitumen stream, treating the diluted bitumen stream in an electrostatic desalter to produce a treated bitumen stream, and separating the treated bitumen stream into a solvent recycle stream and a bitumen product stream. The system may include a combined AC/DC desalter with a control unit for optimizing the treatment process to produce a product bitumen stream using less solvent and smaller separators than conventional bitumen froth treatment plants and processes.
