A heat-treatment apparatus having a combustion chamber (13), an apparatus main body (10) provided with said combustion chamber (13), a combustion burner (20) for supplying a heating gas to said combustion chamber (13), a flue for discharging a combustion gas generated in said combustion chamber (13) to the outside, and a heating vessel stored in said combustion chamber (13), said heating vessel (15) having a bottom and an opening on the top, said opening being opened and closed by a lid (16), and said heating vessel being provided with a communicating member (153) that is communicably open to the above said combustion chamber when said lid is closed. This heat-treatment apparatus can keep the emission gas generated during the treatment, and, waste valuable metals can be efficiently recovered, if contained.An apparatus for a heating treatment which has an apparatus body (10) having a burning chamber (13), a burner (20) for supplying a heated gas to the burning chamber (13), a flue for discharging a combustion gas generated in the burning chamber (13) to the outside thereof, and a heating vessel (15) being placed in the burning chamber (13), wherein the heating vessel (15) has a bottom portion and an open port in the upper portion thereof, the open port may be opened and may be closed with a lid (16), and a communication section (153) is formed for communicating with the upper portion of the burning chamber (13) in the case of the closure of the lid (16). The above apparatus for a heating treatment allows the gas discharged during the treatment to be maintained clean, and also allows the recovery of a valuable metal contained in a waste with good efficiency.
