Abstract
A mobile slurry apparatus for creating a slurry from oil sand ore has a frame and a slurry box supported by the frame. Water is mixed with the ore to form a slurry that is retained in the slurry box. The frame base has a first set of spaced apart support points for supporting the frame in a stationary mode, and a second set of spaced apart support points for supporting the frame in a moving mode. The second set of spaced apart support points is closer together than the first set of support points and defines a lifting region disposed beneath a center of gravity of the slurry apparatus in a moving mode when the slurry box is empty. Thus, a single moving device can be positioned beneath the second set of support points for lifting and moving the slurry apparatus.
