  • Patent number: 8851293
    Abstract: A mined ore processing apparatus to process mined ores, such as oil sands ore, into granular material is disclosed. An ore processor bed receives the ore to be processed. The ore processor bed has a frame supporting several rotating elements each separately driven to provide independent rotation rate and direction from the other. The ore processing bed is operable as a sizing device to decimate mined ore supply into granular material and separating it from rocks and other large lump mineral materials found in situ. The ore processing bed may be oriented to provide an upward inclination, which, when combined with alternating rotating element rotation directions, provides a crushing action to the ore material to crush larger rock. Alternately, a rock crusher is also provided to disintegrate oversized materials.

  • Publication number: 20080308384
    Abstract: A process line for excavating and processing oil sands ore near a mine face. A mobile excavator excavates ore along the length of a mobile mining conveyor. A mobile comminutor receives and comminutes the excavated ore and transfers the comminuted ore to the mobile mining conveyor. The mobile mining conveyor conveys the comminuted ore to a transfer conveyor that conveys the comminuted ore to a mobile slurry facility. The mobile slurry facility combines the comminuted ore with process water to produce a slurry and pumps and conditions the slurry through a hydro-transport pipeline to a mobile extraction facility as a slurry feed. The mobile extraction facility receives the slurry feed and directs the slurry feed and a water stream as inputs to a three stage countercurrent cyclone separator. The cyclone separator produces a bitumen rich stream and a tailings stream.
