Claims (6)

  1. 산화물 광석로부터 금속의 제조 및/또는 슬래그 생성을 위하여 미세하게 분말화된 산화물을 가급적이면 슬래그 형성제와 함께, 물질이 산소를 함유하는 가스와 더불어 아래에 있는 중간구역으로부터의 일산화탄소 및 수소 가스의 연소에 의해 예열되어 가급적이면 용해되는 상부의 산화구역, 예열되어 가급적이면 용해된 산화물질이 탄화수소를 함유하는 물질 및/또는 탄소질물질을 동시 투입하고 또한 열에너지를 주로 플라즈마 발생기에서 가열된 가스에 의해 공급하여서 최소한 부분적으로 환원되는 슬래그욕조로 이루어진 중간 구역과 환원 공정중 형성된 금속이 가라앉고 그 곳으로부터 슬래그가 탕출구를 통해 간헐적으로 빠져나가는 반응 장치의 저부에 있는 하부 구역의 3구역으로 이루어진 반응 장치안에서 처리시키는 것을 특징으로 하는 방법.
  2. 제1항에 있어서, 적어도 산화 및 환원구역을 에워싸는 반응장치의 부분이 반응장치의 내부벽에 형성된 결빙 슬래그층의 도움과 함께 내부적으로 바로 접하는 내화물질로 채워진 수냉판넬에 의해 냉각되어짐을 특징으로 하는 방법.
  3. 제1항 또는 제2항에 있어서, 탄화수소를 함유하는 물질 및/또는 탄소질물질이 플라즈마발생기에 의해 가열된 가스가 공급되는 위치에서 공급되어지는 것을 특징으로 하는 방법.
  4. 제1내지 3항중 어느 한항에 있어서, 탄화수소를 함유하는 물질 및/또는 탄소질 물질과 또한 산소를 함유하는 가스가 반응 장치의 하부에서 도입되고, 또한 산소를 함유하는 가스가 슬래그 욕조의 표면위의 위치에서 공급되어짐을 특징으로 하는 방법.
  5. 제1내지 4항중 어느 한항에 있어서, 반응 장치의 상부 산화구역이 최소한 다른 구역으로부터 부분적으로 분리되고 또한 예열된 물질이 상부 구역으로부터 중간구역으로 떨어져 내리는 것을 특징으로 하는 방법.
  6. 제5항에 있어서, 고온의 배출가스를 반응장치의 정부로부터 회수시켜서 그것의 최소한 일부가 섬광 용해구역을 형성 시키는 적어도 부분적으로 분리된 상부 구역에서 예열되어 가급적이면 용해시키기 위해 이용됨을 특징으로 하는 방법.
