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.

Sizing roller screen ore processing apparatus

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.

Method and apparatus for creating a slurry

A relocatable oil sand slurry preparation system is provided for preparing an aqueous oil sand slurry amenable to pipeline conveyance while producing minimum overall rejects, comprising (a) a relocatable rotary digester for slurrying oil sand and water and digesting oil sand lumps to form a pumpable slurry, the rotary digester having a feed end for receiving oil sand and water, a slurrying chamber comprising a plurality of lifters for slurrying the oil sand and water, and a trommel screen end for screening out oversize rejects from the oil sand slurry which falls through the trommel screen; and (b) a relocatable rejects recirculation unit operably associated with the rotary digester for receiving oversize rejects and delivering the rejects back to the rotary digester for further digestion. In a preferred body, relocatable oil sand slurry preparation system further comprises a rejects crusher for crushing oversize rejects prior to delivering rejects back to the rotary digester.
