ABSTRACT:
A method is disclosed for the separation of oil shale from run of mine (ROM) oil shale containing particles of oil shale and refuse, which comprises conditioning the ROM oil shale with a coupling agent capable of selectively coating the kerogen hydrocarbons in the particulate oil shale to the substantial exclusion of coating the non-hydrocarbonaceous refuse, which coupling agent is one or more compounds selected from the group consisting of an alcohol, at least one carboxylic acid, preferably containing from about 5 to about 28 carbon atoms and a ketone. Combined with said coupling agent is a fluorescent dye in a quantity to make the coated particles of oil shale fluoresce upon excitation to a degree sufficient to distinguish the coated oil shale particles from the substantially non-coated refuse. Exciting (e.g. as with ultraviolet light) the fluorescent dye coupled to the oil shale particles induces fluorescence and enables separating the fluorescing, coated oil shale particles from substantially non-fluorescing, non-coated refuse particles.
