Oil sands are a mixture of sand, water, open-pit mining and in situ. Bitumen that is close to the surface (less than 75 metres) is mined. Approximately 20% of oil sands are recoverable through open-pit mining. Bitumen is extremely thick and too heavy to flow or be pumped, and therefore requires dilution and/or heating during the production process. Open pit mining is similar to coal mining
