Abstract
A system for forming an oil sand slurry from mined oil sand is provided, comprising a slurry preparation tower having an intake opening through which oil sand enters the slurry preparation tower, a first sizer device to comminute the oil sand passing through it, a second sizer device to further comminute the oil sand, and a pump box for receiving oil sand that has passed through the second sizer and feeding it to a pump; at least one conveyor, having a discharge end, for transporting mined oil sand to the slurry preparation tower; a metal detector for detecting a piece of metal in the mined oil sand and transmitting a signal; and a metal rejection device operative to, in response to the signal from the metal detector, reject a portion of oil sand containing the piece of metal before the portion of oil sand enters the slurry preparation tower.
