Oil sands | SuncorSuncor uses large trucks and shovels to extract the oil sands that are near the surface (approx. 130200 ft deep). Hot water is used to separate the bitumen from the sand. This step is called extraction. Bitumen is heated and sent to drums where excess carbon (in the form of petroleum coke) is removed. Vapours from the coke drums are sent to fractionators where they condense into naphtha ...
mineralsandsMineral sand deposits are formed from the erosion and weathering of preexisting igneous rocks such as granite, pegmatite and basalt. Over 60 to 200 million years the combinations of wind and water from ancient rivers and seas have leached the minerals from their past rocks and concentrated them into beach and dune deposits. The result is that, today, mineral sand deposits can occur at varying ...
