Abstract

A method of separating an inorganic material, the method comprising in the following order: a contact process of contacting a processing solution with a composite material, the composite material including a first organic substance that is decomposable by the processing solution, a second organic substance that is not decomposable by the processing solution, and an inorganic material; a separation process of separating the processing solution including a decomposition product of the first organic substance, from a recovered product including the inorganic material and the second organic substance; and a thermal treatment process of subjecting the recovered product to a thermal treatment at a temperature that is equal to or greater than a temperature at which the second organic substance is eliminated.
