Abstract
An aqueous solution suspension or emulsion containing a water-soluble or oil-soluble non-ionic emulsifying agent is useful, when spread over the load-bearing surface of a conveyor carrying bituminous sands, to act as a release agent to promote the clean separation of the tacky sands from the belt when the latter rounds the end roller of the conveyor system and unloads the sands.
