Method and assembly for the recovery of metals from composite materials, in particular from silicon solar modules, thin film solar modules, LCD displays or the like

摘要

The method involves pre-cooling a material (6) to be recycled in a pre-cooling zone (4), which is acted upon by an airflow discharged from a cooling zone such that the material is cooled about 70 Kelvin. The material is crushed in the cooled state. The crushed material is supplied into a non-ferrous metal separator (9). Non-iron parts are removed and discharged after the separation of composite materials. Remaining mixture is supplied to a washing vessel, where vapor-deposited metals are dissolved by acid-based solvents e.g. dilute mineral acids such as nitric or hydrochloric acid. An independent claim is also included for a system for recovery of metals from composite materials.
