Oil sands are flooded and then dredge mined via barges. The mined ore and water form a slurry which is pumped to a floating plant where the slurry may be processed, or the bitumen may be extracted. The process ensures the oil sands do not freeze, making excavation easier during the winter months, and reducing slowdowns due to frost lumps. The process also eliminates the need to use shovels and trucks in the mining pits, resulting in an overall reduction in costs and a reduction in carbon dioxide emissions.
