Process for separating high viscosity bitumen from tar sands | 1984-12-04 | separating bitumen from tar sand; high viscosity bitumen; tar sand; bitumen recovery; patent | A novel process for separating high viscosity bitumen from tar sand. The process includes grinding the tar sand to obtain phase disengagement of the bitumen phase from the sand phase and thereafter using flotation techniques to obtain phase separation of the bitumen phase from the sand phase. Phase ... |

Bitumen recovery from tar sands | 1984-09-11 | Patent; Bitumen recovery; Tar sands; Kerosene; Flotation cell; Bitumen | A process for recovering bitumen from tar sands wherein the tar sands are pretreated with a diluent, such as kerosene in the preferred embodiment, to lower the viscosity of the bitumen such that it is in the range of about 5 to about 20 poise at the digestion temperature. The tar sands are then dige... |
