Abstract

Oil shale impurities prevent its direct usage as a source of energy. Removing or reducing of these impurities before retorting can reduce the cost of oil shale processing. In that regard, pretreatment of oil shale by flotation represents one of the favorable solutions. Therefore, in this work, (a) microscopic examinations were carried out to study the mineralogical characteristics of oil shale sample and (b) flotation of oil shale was used to separate organic matter (kerogen) from associating gangue by adjusting the flotation pH, stirring speed and pulp density without adding a collector. The results of oil shale characterization showed that kerogen content in the studied sample was 10%, while the results of flotation experiments proved the possibility of oil shale upgrading to about 20% kerogen with recovery reaching to more than 70%.
