Oil Sands Mining | Student Energy

Open pit mining is similar to coal mining operations – large shovels scoop the oil sand into trucks that then take it to crushers where the large clumps of earth are broken down. This mixture is then mixed with water to form a slurry that is transported to a plant, where the bitumen is separated from the other components in a froth process.
