Zusammenfassung:	PCT No. PCT/DE91/00682 Sec. 371 Date Jul. 13, 1992 Sec. 102(e) Date Jul. 13, 1992 PCT Filed Aug. 29, 1991 PCT Pub. No. WO92/05215 PCT Pub. Date Apr. 2, 1992.The present invention relates to a process for the recovery of metals and coatings present on the metals from composite materials by means of the treatment of the composite materials with specific solvents at elevated temperatures, whereby the coating is dissolved and recovered from this solution while the metal is quantitatively separated from the solution in a pure state, after which it can be recycled.
