Abstract
A process of regulating the water content of water-fluidized oil sand ore during processing of the ore is disclosed. The weight (mo) of a sample charge of oil sand ore having a bulk volume (Vt) is determined. The inter granular voids of the sample charge are then filled with water, and the weight (ma) of the added inter granular water is determined. A target specific gravity value (SGmix) is selected for the fluidized oil sand ore. The volume of additional water, ΔV, to add to a sample charge of bulk volume Vt, to achieve the target specific gravity value (SGmix) is calculated by solving the following equation:The determined volume ΔV of additional water per bulk volume Vt of oil sand ore to be processed is added to the oil sand ore, producing water-fluidized oil sand ore. The ore is then processed to concentrate the bitumen.
