  • Patent number: 8646615
    Abstract: A screening disk for use on a roller of a roller screen for screening an ore feed is disclosed, which includes first and second opposing side working surfaces, and provisions for mounting the screening disk on a shaft of the roller. At least one of the first and second side working surfaces has a plurality of protrusions operable to extend outwardly into an interstice between the applicable side working surface and a side working surface of an adjacent mounted screening disk. A spacer may be disposed in the one interstice for confining an extent of the one interstice to a region disposed generally between the third working surface and the shaft. A screening disk may have a keyway configured to receive a key for coupling the body of the screening disk to the shaft for rotation therewith.

  • Patent number: 8317116
    Abstract: A method and process line apparatus for processing a sized ore feed excavated from an ore deposit is disclosed. The method involves disposing a processing apparatus in a processing apparatus position relative to the ore deposit, and disposing a first mobile conveyor to receive a sized ore feed at a receiving location located along a length of the first mobile conveyor. The first mobile conveyor is operable to convey the sized ore from the receiving location to a discharge end of the first mobile conveyor. The method also involves disposing a second mobile conveyor to receive the sized ore from the discharge end of the first mobile conveyor at a transfer location along a length of the second mobile conveyor and to convey the sized ore from the transfer location to the processing apparatus. The first and second mobile conveyors are oriented at an operational angle between a length of the first mobile conveyor and a length of the second mobile conveyor.

  • Patent number: 8025341
    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.
