본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음

Claims (9)

  1. 규소와 알칼리 금속 불화물을 포함하는 반응 혼합물로부터 규소를 재생하기 위한 방법에 있어서, 전술한 알칼리 금속 불화물을 알칼리 고금속 염화물의 수용액으로 침출(leaching)함을 포함하는 방법.
  2. 제1항에 있어서, 알칼리 토금속 염화물이 염화칼슘, 염화마그네슘 및 염화바륨으로 구성된 그룹으로부터 선택되는 방법.
  3. 제2항에 있어서, 알칼리 금속 불화물이 불화나트륨이고 알칼리 토금속 염화물 염화칼슘인 방법.
  4. 제3항에 있어서, 염화칼슘 수용액이 물과, 중량으로 5%에서 수성혼합물을 포화시키기에 충분한 량의 염화칼슘을 포함하는 방법.
  5. 제3항에 있어서, 염화수소산, 옥화수소산, 과염소산, 질산 및 취화수소산으로 구성된 그룹으로부터 선택된 산으로 pH를 1-5 사이로 조절하는 방법.
  6. 제4항에 있어서, (a) 염화칼슘 수용액을 규소와 불화나트륨의 혼합물에 불화물 이온의 총량에 대해 화학당량적으로 초과된 칼슘이온을 구비하도록 첨가하여 수성 슬러리를 형성하고; (b) 전술한 수성 슬러리의 불화나트륨이 염화칼슘과 반응하여 불용성 불화칼슘을 형성하게 하고; (c) 전술한 규소를 중력에 의해 침전시켜 전술한 슬러리로부터 규소를 분리하고; (d) 가만히 다루어서 슬러리를 제거하고 규소를 믿고; (e) 규소를 세척하여 불화칼슘의 잔유물을 제거하는 과정을 포함하는 방법.
  7. 제6항에 있어서, 염화칼슘 수용액이 륨과, 5%에서 상기 용액을 포화시키기에 충분한 량의 염화칼슘을 포함하는 방법.
  8. 제6항에 있어서, 염화칼슘 수용액이 산을 함유하는 방법.
  9. 제7항에 있어서, 산이 염화수소산인 방법.
