Abstract:
The present invention relates to an improved bitumen recovery process from oil sands. The oil sands may be surface mined and transported to a treatment area or may be treated directly by means of an in situ process of oil sand deposits that are located too deep for strip mining. Specifically, the present invention involves the step of treating oil sands with a glycol ether amine described by the following structure: R—(OC2H4)x—NH2 or R—(OCH2CH(CH3))y— NH2 wherein R is a C1 to C6 alkyl group or a phenyl group and x and y independently are 1 to 3.
