Abstract
Description
炉体を備え、この炉体は内側に溶融プールを含むと共に、ガス・ノズル、供給ポート、粗銅排出ポート、及びスラグ排出ポートが設けられており、
そのガス・ノズルは炉体の側壁に配置されており、溶融プールの中間部へ至る。
炉体を備え、この炉体は内側に溶融プールを含むと共に、ガス・ノズル、供給ポート、粗銅排出ポート、及びスラグ排出ポートが設けられており、
そのガス・ノズルは炉体の側壁に配置されており、溶融プールの中間部へ至る。
炉体を備え、この炉体は内側に溶融プールを含むと共に、ガス・ノズル、供給ポート、粗銅排出ポート、及びスラグ排出ポートが設けられている。
図1に示される生産装置では、銅溶解溶融スラグ1はランナーを通じて供給ポート413を介して炉体4へ導入され、コークス2はランナーを通じて供給ポート413を介して比例的に添加されると共に、加圧された窒素ガス3は、炉体4の二つ側壁に配置されて溶融プールに浸漬されたガス・ノズル411を介して連続的に導入された。材料は混合されて続いて反応した。分離されたスラグ層8と粗銅層9とが炉体4内に形成されて、余剰で未反応のコークスが未反応コークス層7を形成した。
例2
分離された粗銅と新たなスラグとは、例1の方法により、800 kPaの圧力の窒素ガスにより得られ、コークスのカーボン含有量に対する銅溶解溶融スラグの酸素含有量に対する質量比(C/O)は(0.1-0.35):1になった。
例を挙げての上述の説明は、単に本発明の方法及びその核となる概念の理解を助けるだけである。幾つかの改良例及び変更例が本発明の趣旨から逸脱することなく当業者によりなし得ることが示唆されており、そのような改良例及び変更例の全ては本発明の特許請求の範囲によって保護された保護範囲の範疇にある。
炉体を備え、この炉体は内側に溶融プールを含むと共に、ガス・ノズル、供給ポート、粗銅排出ポート、及びスラグ排出ポートが設けられており、

炉体を備え、この炉体は内側に溶融プールを含むと共に、ガス・ノズル、供給ポート、粗銅排出ポート、及びスラグ排出ポートが設けられており、
そのガス・ノズルは炉体の側壁に配置されており、溶融プールの中間部へ至る。
生産装置において、銅溶解溶融スラグ、カーボン含有還元剤、及び加圧した不活性ガスを混合し、それに反応が続いて粗銅及び後反応スラグを得て、その不活性ガスの圧力は100kPa乃至800kPaである。
本発明の一例においては、銅溶解溶融スラグとカーボン含有還元剤は生産装置へ導入され、加圧された不活性ガスは100kPa乃至800kPaの圧力において生産装置へ充填される。次いで、これらの材料が混合されて反応を実行し、それによって粗銅及び後反応スラグを得る。
炉体を備え、この炉体は内側に溶融プールを含むと共に、ガス・ノズル、供給ポート、粗銅排出ポート、及びスラグ排出ポートが設けられている。
図1に示される生産装置では、銅溶解溶融スラグ1はランナーを通じて供給ポート413を介して炉体4へ導入され、コークス2はランナーを通じて供給ポート413を介して比例的に添加されると共に、加圧された窒素ガス3は、炉体4の二つ側壁に配置されて溶融プールに浸漬されたガス・ノズル411を介して連続的に導入された。材料は混合されて続いて反応した。分離されたスラグ層8と粗銅層9とが炉体4内に形成されて、余剰で未反応のコークスが未反応コークス層7を形成した。
分離された粗銅と新たなスラグとは、例1の方法により、800 kPaの圧力の窒素ガスにより得られ、コークスのカーボン含有量に対する銅溶解溶融スラグの酸素含有量に対する質量比(C/O)は(0.1-0.35):1になった。
