Tar Sands Mineral Deposits in Nigeria with their Locations

The bitumen in which the oil is extracted from cannot be mined freely or pumped in its natural state from the ground so it is mined together with the deposits of tar sand through open pit techniqu the open cast strip mining method is mostly used After mining the bitumen in the oil sands is separated from the sand clay and water that...

Bitumen mining Britannica

Bitumen dense highly viscous petroleum-based hydrocarbon that is found in deposits such as oil sands and pitch lakes natural bitumen or is obtained as a residue of the distillation of crude oil refined bitumen In some areas particularly in the United States bitumen is often called asphalt though that name is almost universally used for the road-paving material made from a mixture of...

Differences between underground mining and open pit mining

Oil Sands Extraction and Processing

Bitumen can be extracted using two methods depending on how deep the deposits are below the surface in-situ production or open pit mining In-situ Production In-situ extraction methods are used to recover bitumen that lies too deep beneath the surface for mining...

Methods For Separation of Bitumen From Oil Sands

Nov 04 2011 0183 32 During open pit mining the viscous oil is recovered along with the ore This means that a process of separation must then be undertaken Currently the most common separation method for the Athabasca oil sands deposit is the Clark Hot Water Extraction CHWE process In this process the mined ore is first crushed or ablated...

Digging deeper Mining methods explained Anglo American
