ABSTRACT:
This invention is a method of recovering an expensive bearing lining alloy from a multilayer bearing material comprising the alloy bonded to a steel backing, possibly through a pure aluminium foil. The multi-layer scrap material is heated sufficiently for severance of the bond between the components to be started, and then is given repeated mechanical shocks which complete the severance of the components which can then be separated from one another by a magnetic method, or possibly by a gravitational method.
