چکیده (انگلیسی):

Evaluation possibility of a low quality Egyptian oil shale from Wadii El-Nakhil, Red sea region as an alternative clean fuel by flotation technique was investigated. Oil shale sample was characterized using XRD and FTIR analyses to determine its mineral content and surface characteristics. XRD analysis showed that the non-clay minerals present in the oil shale sample include; quartz, siderite, apatite, anhydrite and calcite. The clay mineral is mainly represented by kaolinite while the organic matter is 30%. The effects of frother and collector dosages and pulp Ph on the flotation performance were investigated using kerosene as a collector. The pine oil or MIBC were used as frothing agents. By using 5g/kg kerosene as a collector and 9g/kg of MIBC as a frother at pH 9, a kerogen of 38% with recovery of 88.5% was obtained from oil shale sample of 28%.
