Treating of froths produced in extraction plants processing surface‐mined oilsand presents an interesting and challenging array of problems. Much of what we do to the feed ore to maximize recovery of bitumen creates surfactant/biwettable solids mixtures that stabilize water‐in‐oil emulsions. These persist despite our most strenuous attempts to break them. Temperature and solvent selection both influence the performance of froth treatment processes. However, often we do not look at the broader implications of either in new or expanding ventures. This paper presents another perspective, showing how both temperature and solvent selection influence the outcome of froth treatment.
