Abstract

Provided are a separation method and a separation device used therein with which plastic and aluminum can be separated. The separation method includes a first heating step, and a first heat insulation step. In the first heating step, a processing target, which is accommodated in a container and contains aluminum and one or more types of plastic, is heated to a first temperature. The first temperature is a temperature that is less than the melting point of the aluminum and is greater than or equal to the melting point of at least one type of the plastic. Thus, the at least one type of plastic is melted. In the subsequent first heat insulation step, the processing target is kept at the first temperature. The heat insulation is continued until the aluminum is precipitated in the container and separated from the melted plastic.
