Abstract
【解決手段】電気炉6は、被処理物Wの溶融物から電気による加熱処理によって更に金属を分離させ、被処理物Wの溶融物であるスラグSに含有される金属を回収することできる。また、電気炉6は回転炉2と連絡シュート4を介して接続されているため、被処理物Wは回転炉2にて燃焼処理されてスラグSとなった後、直ちに電気炉6へ投入され、金属回収を効率的に行うことができる。更に、回転炉2での燃焼処理による熱を電気炉6における加熱処理に有効利用することができ、エネルギー効率を向上させることができる。また、コークス供給装置22Aより還元剤を供給し、電気炉6内のスラグS中に含まれる金属酸化物を還元反応させることによって、より多くの金属を回収することができる。
