Abstract: A processing apparatus capable of separating and recovering resins and metals, respectively, from an object being processed, which has resins and metals as its constituent, comprises a first gastight area (102), in which temperature and pressure are regulated so as to permit selective thermal decomposition of resins from the object (150) being processed, a second gastight area (103), which is partitioned from the first gastight area by an openable and closeable partition (105C) and in which temperature and pressure are regulated so as to permit selective vaporization of metals from the object, first recovering chamber (111) connected to the first gastight area for recovering gases produced by thermal decomposition of resins, and second recovering chamber (115) connected to the second gastight area for recovering vaporized metals.

Abstract: A process as disclosed for constructing a furnace for open chambers for baking carbonaceous blocks, comprising arranging a plurality of chambers in a series or in two parallel series, each chamber being defined by lateral partitions and transverse partitions, disposing the plurality of chambers within an independent concrete casing formed by a floor and lateral wall portions having disposed thereof a plurality of vertical buttresses and compressively prestressing the vertical buttresses in the vertical direction. A horizontal force may also be applied to the upper part of the transverse partitions.
