Abstract
In Estonia, oil shale is used as a fuel for producing energy and as raw material for processing shale oil. Concentration plants at mines must guarantee required oil shale quality and quantity parameters. The processing rock material (run-of-mine) is the mineral composition, the quality of which depends on geological conditions and technology in mine. Mathematical description and data analysis are performed on working processes from working place (face) to a concentration plant: extraction, crushing, screening and concentration. A mathematical model for a concentration plant was created based on these studies. This model allows determining the optimum parameter kinds of trade oil shale and helps to design processing flow sheet.
