open pit method of mining bitumen

Tar Sands

Open pit mining Mining Methods 5 Open pit mines are used to exploit low grade, shallow ore bodies. However, some pits are quite deep – about 1 km. The mining rate is greater than 20,000 tonnes per day (tpd) but is usually much greater. Some pits operate at a rate of more than 100,000 tpd Open pit mining results in two waste streams: waste ...

How is oil extracted from tar sands?

Open-pit mining, also known as open-cast or open cut mining, is a surface mining technique of extracting rock or minerals from the earth by their removal from an open-air pit, sometimes known as a borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining.Open-pit mines are used when deposits of …

Surface mining planning and design of open pit mining

A great deal of processing is required to separate this bitumen from the associated soil and other debris. One of the two most common ways to recover bitumen from oilsands is through open pit mining of deposits which lie near the surface. Oil sands deposits which lie within 75 meters of the surface are typically recovered via mining.

Environmental Risks of Mining

Only 20 percent of bitumen can be extracted using open pit mining methods, which involves large scale excavation of the land with huge hydraulic power shovels and 400-ton heavy hauler trucks. Surface mining leaves toxic tailings ponds. In contrast, in situ uses more specialized techniques such as steam-assisted gravity drainage (SAGD).

To extract the bitumen in the oil sands, conventional oil drilling techniques cannot be used because bitumen is too heavy to be pumped and sticks to sand grains. Therefore other extraction techniques have been developed. The most common methods to extract bitumen are open-pit mining and in-situ, which is Latin for 'in place'.
