Description
請求項1に記載の発明によれば、焼却灰に炭素源とシリコン源を添加して焼却灰の成分を調製すると共に、塩基性酸化物と酸性酸化物をそれぞれ添加して焼却灰の塩基度を調製して、成分調製と塩基度調製された前記焼却灰を1600〜1700℃に加熱して溶融させることによって、溶融した焼却灰を比重によって下から順に銅、鉄、及び塩基度が1.1〜1.6に調製された溶融スラグの各層に溶融分離させることができるので、焼却灰から高純度の銅と鉄を取出すことができ、更に、溶融スラグの融点が高くなることによって溶融スラグ中の有害金属の含有をほとんどなくすことができる。

Claims (3)
- 廃棄物を焼却処理した後に残った焼却灰を加熱して溶融処理する焼却灰の溶融処理方法であって、
焼却灰に炭素源とシリコン源を添加して焼却灰の成分を調製すると共に、塩基性酸化物と酸性酸化物をそれぞれ所定の割合で添加して焼却灰の塩基度を調製して、成分調製と塩基度調製された前記焼却灰を1600〜1700℃に加熱して溶融させ、
溶融した前記焼却灰を比重によって下から順に銅、鉄、及び塩基度が1.1〜1.6に調製された溶融スラグの各層に溶融分離させる、
ことを特徴とする焼却灰の溶融処理方法。 - 前記溶融スラグはSiO2、CaO、Al2O3、MgOを主成分とし、前記溶融スラグを取出して鋳型に鋳込んだ後に徐冷して結晶化し、塩基度が1.1〜1.6の人工岩石を生成する、
ことを特徴とする請求項1に記載の焼却灰の溶融処理方法。 - 前記焼却灰は、廃車からリサイクル可能な部材を選別して取り除いた残りの廃車ガラをシュレッダーによって細かく粉砕してシュレッダーダストとし、このシュレッダーダスト又は該シュレッダーダストから樹脂成分を分解処理した後に残った残渣を焼却処理した後に残る焼却灰である、
ことを特徴とする請求項1に記載の焼却灰の溶融処理方法。
