Abstract

A process for the separation and recovery of bitumen from oil sands containing bitumen and coarse and fine solids in a separation vessel which comprises the steps of slurrying 30 to 70% by weight oil sands in water, heating said slurry to a temperature in the range of about to about 90°C, adding an effective amount of conditioning agents and air to said slurry and intimately admixing said conditioning agents and air with the slurry, preferably in a pipeline, feeding said conditioned and aerated slurry into said separation vessel and recovering bitumen as a froth. The conditioned and aerated slurry is introduced underwater into the separation vessel in a froth flotation-gravity separation zone wherein bitumen floats to the surface as a froth and coarse solids and a portion of fines fall by gravity to a bottom discharge portion of the vessel. The conditioning agents have the characteristics of kerosene and methyl-isobutyl-carbinol in an effective amount in the range of about 200 to 400 ppm and said kerosene and methyl-isobutyl-carbinol are present in the ratio of about 2:1. The separation vessel has a froth flotation-gravity separation zone and a quiescent zone adjacent thereto with at least one cone bottom for collecting and removing sand and fine solids.
