Title Ambient froth flotation process for the recovery of bitumen from tar sand
Date 1984-01-10
Description A method for upgrading the bitumen content of tar sands, wherein a raw tar sand slurry admixture of tar sands, water, collectors, and dispersing/wetting agents is milled; conditioned and then separated by a series of froth flotations at ambient temperatures from about 2.degree. C. to about 25.degree. C. to recover a concentrated bitumen tar sand product which may be processed by conventional means to recover oil from the bitumen. Enhanced recovery of bitumen may be accomplished by moderate heating in one or more of the flotation zones to about 50.degree. C. The method permits recovery and recycle of various components used in processing of the tar sand.
