ABSTRACT:
Diluted bitumen emulsion, the aqueous phase of which carries undissolved mineral particles, is upgraded by resolving it by subjecting it to a unidirectional electric field established between an energized electrode and an aqueous material surface serving as an electrical ground. The emulsion is introduced below the level of such surface and allowed to rise. A potential gradient is provided which is sufficient to cause coalescence of the aqueous material in the emulsion as soon as the emulsion breaks the aqueous material surface, the emulsion thereby being resolved at such surface.
