The most common methods to extract bitumen are open-pit mining and in-situ, which is Latin for ‘in place’. The method used to extract bitumen from the oil sands depends on the depth of the deposit. If the deposit is near the surface, the oil sands is mined and sent to a bitumen processing plant.

Open Pit Mining an overview ScienceDirect Topics

8.2.3.1 Open pit mining. Open pit mining refers to mining directly on the ground surface, thereby producing an open pit. This method is practical and cost-effective when the uranium ore is located near the surface (e.g., within 100 m). Underground mining and ISL methods may be considered for sites that have uranium ores at deeper depths.

Open-Pit Mining Definition Anglo American

Open-pit mining, also known as opencast mining, is a surface mining technique that extracts minerals from an open pit in the ground. Open-pit mining is the most common method used throughout the world for mineral mining and does not require extractive methods or tunnels. This surface mining technique is used when mineral or ore deposits are

Surface Mining Techniques used in the Oil Sands Oil

2016-5-1  Surface mining is defined as the extraction of ore from an open pit or burrow. Surface mining is sometimes known as open-pit, open-cut or open-cast mining and is only commercially viable if the deposit is located relative close to the surface. Less than 20% of Alberta's bitumen reserves are close enough to the surface to be mined.

Bitumen within seventy-five (75) meters of the surface is open-pit mined. First, huge clumps of oil sands are shoveled into large trucks. They are then taken to crushers, where they are broken down and mixed with heated water to separate the bitumen from the sand. Once the bitumen is released, it is sent for further processing.

Reading: Open-Pit Mining Geology Lumen Learning

Open-pit mining, or open-cast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful minerals or rocks are found near the surface; that is
