oil shale National Geographic Society

Mar 04, 2013· Oil shale is a type of sedimentary rock that is rich in kerogen. Kerogen is a part of rock that breaks down and releases hydrocarbons when heated. Hydrocarbons are substances made entirely of hydrogen and carbon. Petroleum and natural gas are probably the most familiar hydrocarbons. The hydrocarbons in oil shale can be used as an alternative to petroleum or

Utilising selective extraction, crushing and separation of

Dry separation with crushing buckets helps to accelerate the separation process as the loading and crushing for the power plants take place at the same brown coal, oil shale etc. The dry enrichment of the rock mass results in a higher calorific value of the oil shale and the separated waste rock can be left at site. This separation feature

Shale oil extraction Wikipedia

Shale oil extraction is an industrial process for unconventional oil production. This process converts kerogen in oil shale into shale oil by pyrolysis, hydrogenation, or thermal dissolution.The resultant shale oil is used as fuel oil or upgraded to meet refinery feedstock specifications by adding hydrogen and removing sulfur and nitrogen impurities.

Dry Beneficiation Of Rock Phosphate CREATOR

Abstract. Beneficiation of phosphate ores by electrostatic processes has been demonstrated by various researchers since the 1940’s.Separations have been achieved by removing silica from phosphates, and withfewer examples of calcite and dolomite from phosphate. Limitations on conventional electrostatic systems include low capacity, the need for multiple stages, and operational problems caused
