The suitable surface active agent was added to decrease the liquor surface tension of bae yer red mud slurry so as to achieve the aim of decreasing mud moisture content after the filtration.
Raffinate loses the emulsifying ability and low interfacial tension property, so the acidic components in heavy oil are the major active component for emulsification of basic water.
