Mobile oil sands mining system

A process line for excavating and processing oil sands ore near a mine face, the process line comprising:

• a mobile excavator for excavating ore along the length of a mobile mining conveyor;
• a mobile comminutor for receiving and comminuting the excavated ore and transferring the comminuted ore to the mobile mining conveyor;
• the mobile mining conveyor conveying the comminuted ore and discharging the comminuted ore to a discharge point proximate a discharge end of the mobile mining conveyor,
• the mobile mining conveyor including a location sensor for locating the discharge point of the mobile mining conveyor with respect to a transfer conveyor;
• the transfer conveyor conveying the comminuted ore to a mobile slurry facility;
• at the mobile slurry facility combining the comminuted ore with process water to produce a slurry and pumping and conditioning the slurry through a hydro-transport pipeline to a mobile extraction facility as a slurry feed;
• at the mobile extraction facility receiving the slurry feed and directing the slurry feed and a water stream as inputs to a three stage countercurrent cyclone separator;
• the cyclone separator producing a bitumen rich stream and a tailings stream;
• the bitumen rich stream being directed to a froth concentration unit;
• the froth concentration unit separating the bitumen rich stream into a bitumen product stream, a recycled water stream and a fine tailings stream;
• the fine tailings stream being combined with the tailings stream to produce a tailings product stream;
• the tailings product stream being directed to a tailings treatment facility;
• the tailings treatment facility receiving the tailings product stream and combining the tailings product stream with an additive to produce a treated tailings stream;
• the treated tailings stream being directed to a tailings pond;
• the treated tailings stream being separated into a dry tails phase and a water phase;
• and
• the water phase being collected at the tailings pond and recycled as industrial process water.
