“…This is probably a consequence of the common use of these procedures to improve the oil yield in the Fisher assay; Fisher assay procedures are applied most successfully to Green River shales. More recently, investigators have studied benef iciation of eastern shales [112,[115][116][117][118][119][120].…”

“…Comminution is used frequently in conjunction with other separation techniques, particularly sink-float and flotation. Reduction to 10-20 m has been shown to give most efficient separations [112], though Tsai and Lumpkin [120] report equally good separation at 150-500 m. Datta and Salotti [111,122] report that western shales fractured easily but eastern did not; they also report successful separation by comminution only.…”

“…Sink-float procedures in various media use the density difference of the mineral and organic components for separation. Variations of the usual gravity separation include use of heavy media [113], cyclones [111], and hydrocyclones [120]. Larson [113] notes that coarse grinding ( 3 inch top size) followed by heavy media suspension is successful in liberating increased amounts of high grade shale.…”

“…Flotation using shale oil as a collector showed some selectivity but recovery was very low. For the same oil shale deposit, Tsai and Lumpkin [5] found that froth flotation is capable of upgrading oil shale and improving the oil yield by Fischer assay from 0.117 to 0.175 1/kg at 75% organic recovery. The types of frother and collector affected the float yield, but they had no significant effect on the grade of the float.…”

The necessity to satisfy the increasing demand for energy and the progressive depletion of crude oil resources have renewed interest in oil shale as an alternative fuel resource. This paper aims at determining the potential for upgrading El-Nakheil oil shale, Egypt, using froth flotation. Samples were prepared by comminution followed by sieving into different size fractions. The flotation behavior of the material and extent of cleaning were studied with respect to non-ionic and ionic collectors of anionic and cationic types. The organic rich portions of samples could not be rendered sufficiently hydrophobic by the collectors used and the selectivity towards surfactant was very low.

“…Previous studies indicate that flotation is inexpensive, it reduces the amount of mineral ash, and it enriches the material in useful minerals (Tsai and Lumpkin 1984;Cheng et al 2017). However, until now, only a few articles have concentrated on oil-shale flotation.…”

In the future, oil shale will be an important energy resource. Froth flotation is a new method increasing the usability of oil shale. In this paper, oil shale samples were characterized based on their mineral composition, proximate analysis, ultimate analysis, size distribution, and density analysis. In addition, the flotation performance of oil shale was investigated. The effects of pulp concentration, agitation speed, aeration rate, and the type of reagents on the flotation performance were explored. Analysis of the samples' characteristics indicates that cleansed oil shale is highly usable. The optimal flotation performance occurred for a pulp concentration of 50 g/L, a collector dosage of 1000 g/t, a frother dosage of 300 g/t, an agitation speed of 1900 rpm, and an aeration rate of 160 L/h. Froth flotation is a mature method and is widely used, and thus, it can be used to improve the industrial production of oil shale.
