Description
先ず、マグネタイト濃縮層の存在と銅粒子の沈降状態について以下のように調査した。
内径17mmのアルミナ製タンマン管の底に銅製錬の実操業で発生したマット20gを装填し、その上に同じく実操業で発生したスラグ40gを載せた。次いで、タンマン管を黒鉛るつぼ内に立てた状態で入れ、この黒鉛坩堝に耐熱ボードで蓋をし、電気炉内に立てた状態で設置した。
タンマン管に装填したスラグ40gとマット20gに対して攪拌処理を施さなかったこと以外は、実施例1と同じ方法で過熱し冷却した。冷却後のタンマン管を、実施例1と同じ方法で輪切りにし、スラグとマットの界面を光学顕微鏡で観察した。
Claims (2)
- 銅製錬により発生したスラグを保持した保持炉内において、該保持炉内に設けた攪拌装置により該スラグを攪拌するに際しては、該攪拌装置の先端部を該スラグとマットの界面付近に位置させて攪拌し、該スラグ中の銅粒子を沈降させることを特徴とする銅製錬スラグからの銅の回収方法。
- 1cm/sより大きな流速の旋回流を生じさせるように攪拌することを特徴とする請求項1記載の銅製錬スラグからの銅の回収方法。
