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. The bitumen rich stream is directed to a froth concentration unit that separates the bitumen rich stream into a bitumen product stream, a recycled water stream and a fine tailings stream. The fine tailings stream is combined with the tailings stream to produce a tailings product stream that is directed to a tailings treatment facility. The tailings treatment facility receives the tailings product and combines the tailings product with an additive to produce a treated tailings stream that is directed to a tailings pond for separation into a dry tails phase and a water phase that may be collected and recycled as industrial process water.
