A dry electrostatic process for beneficiating Eastern oil shales was investigated. Scanning electron microscope analysis showed a need to grind the shale to an average particle size of less than 5 μm for nearly complete liberation of mineral inclusions from the organic matrix. The carbonaceous and noncarbonaceous components of shale were imparted positive and negative surface charges, respectively, with a copper tribocharger. Tests in a batch electrostatic separator showed kerogen enrichments from 12 percent in feed up to a value of 34 percent in the product stream. The efficacy of beneficiation was found to be strongly dependent on hydrodynamic conditions, such as particle velocity, particle concentration in the carrier gas, electric field strength, geometry of the separator, etc. Furthermore, the extent of separation was found to be limited by a strong cohesive force acting between the finely ground shale particles which results in the formation of agglomerates. |
