Method for separating inorganic material, method for producing recycled material, and method for removing organic substance

摘要

A contact step of contacting a composite material containing a first organic substance that is decomposed by the treatment liquid, a second organic substance that is not decomposed by the treatment liquid, and an inorganic material; and a decomposition product of the first organic substance A separation step of separating the treatment solution containing the inorganic material and the second organic matter, and a heat treatment step of heat-treating the recovery product at a temperature equal to or higher than the temperature at which the second organic matter disappears. , In this order, a method for separating inorganic materials.
