We claim: 1. A process for separating bitumen from a bitumen feed comprising a mixture of bitumen, water and mineral, the process comprising: a) supplying said bitumen feed to an inclined plate separator (IPS) to produce an IPS overflow comprising a first bitumen rich stream and an IPS underflow comprising a first bitumen lean stream; b) supplying said IPS underflow to a cyclone to produce a cyclone overflow comprising a second bitumen rich stream and a cyclone underflow comprising a second bitumen lean stream; and, c) recycling said cyclone overflow for blending with the feed to said IPS. 2. The process of claim 1 wherein said bitumen feed comprises a bitumen froth formed by an oil sands extraction process. 3. The process of claim 2 wherein said bitumen froth is treated in a second inclined plate separator (IPS) prior to being introduced into said cyclone. 4. The process of claim 3 wherein an underflow of said second IPS is introduced into said cyclone. 5. The process of claims 1 wherein said bitumen feed is diluted with a solvent. 6. The process of claim 5 wherein said solvent is naphtha. 7. The process of claim 1 wherein said first bitumen rich stream of said IPS is coupled to a bitumen product stream. 8. The process of claim 1 wherein said first bitumen rich stream of said IPS is coupled to a bitumen product stream.
