An oil sand mining operation is a complex process that produces synthetic crude oil from the processing of bitumen in ore. Fig. 1 illustrates how the ore is mined and subsequently transported by truck to a hopper from which the ore is crushed and stored in a surge pile, which feeds a downstream processing plant, wherein bitumen is extracted ...

The open-pit method for the development of the shallow deposits of natural bitumen is economically beneficial. The production of oil from tar sands is more economical. The favorable geological conditions are shallow depths of occurrence and gentle slopes of the productive bituminous sandstone formations.

There are two primary extraction methods for oil sands: open-pit mining and in-situ mining. The technique used depends on the depth of the deposit. For example, in-situ mining is used when bitumen lies too deep beneath the surface for open-pit mining. Injection of steam is used in both methods to heat the bitumen, which serves to make it …
