Oil Sands Mining - Bitumen in Oil Sands

Oil sands mining is quite different than drilling for oil far beneath the earth's surface. In oil sands mining, a mix of oil and sand is removed from about 100 to 150 feet below the surface using heavy equipment. The sand is made up of sand, bitumen, clays, and water. Bitumen is the key ingredient.
