Abstract:
A processing apparatus for processing an object that comprises a resin and a metal as constituent members, comprising:a first gas tight zone provided with a temperature adjusting means and a pressure adjusting means for adjusting a temperature and a pressure in the first gas tight zone so that the resin of the object being selectively pyrolyzed;a second gas tight zone separated by a partition capable of opening and closing from the first gas tight zone, and the second gas tight zone being provided with a temperature adjusting means and a pressure adjusting means for adjusting a temperature and a pressure in the second gas tight zone so that the metal in the object being selectively vaporized;a gas decomposition chamber for processing gases generated by pyrolysis of the resin, and the first processing means being connected to the first gas tight zone;a recovering chamber for recovering the metal vaporized from the object, the recovering chamber connected to the second gas tight zone;an oxygen concentration sensor in the first gas tight zone; anda carrier gas introducing gas value for adjusting the oxygen concentration in the first gas tight zone in response to the measured oxygen concentration.
