Process. Oil sand is a mixture of bitumen sand and water. Because it does not flow like conventional crude oil it must be mined or heated underground before it can be processed. Our oil sands business recovers bitumen through surface mining and steam injection technologies and upgrades it into refinery-ready crude oil products.
Environmental concerns regarding oil sands mining focus on the toxic waste byproduct of the extraction process and land disturbance. After the sand is brought to an extraction plant it undertakes a dilution process in which it is mixed with hot water and chemicals so that it may flow freely into pipelines .
Introduction. Sand and gravel are used extensively in construction. In the preparation of concrete for each tonne of cement the building industry needs about six to seven times more tonnes of sand and gravel USGS 2013b. Thus the worlds use of aggregates for concrete can be estimated at 25.9 billion to 29.6 billion tonnes a year for 2012 alone.

Currently 20 of oil sands reserves are accessible via mining techniques. Large shovels scoop the oil sand into trucks which then move it to crushers where the large clumps of earth are processed. Once the oil sand is crushed hot water is added so it can be pumped to the extraction plant. At the extraction plant more hot water is added to .
Aug 06 2020 Oil sands are a combination of sand clay and water that contain a heavy crude oil variant called bitumen. 1 But this complex hydrocarbon is almost solid at room temperature and does not flow without extensive processing. 2 Subsequently there are two ways to extract the bitumen mining or in situ. 3 Both are complex energy-intensive and expensive processes. 3 As a result oil sands .
