【摘要】：采用高溫快速還原焙燒-磁選工藝從銅冶煉渣回收鐵,系統(tǒng)研究了堿度(Ca O/Si O2)、還原溫度、還原時間、還原劑用量等因素對磁選金屬鐵粉質量的影響。結果表明,銅渣中的鐵主要以鐵橄欖石形式存在,其次為磁鐵礦;在堿度(Ca O/Si O2)0.6、焦粉配比12%、還原溫度1 300℃、還原時間30 min、銅渣粒度-0.074 mm粒級占95%、磁場強度0.08 T的條件下,可得到鐵品位91.10%、金屬化率94.27%的金屬鐵粉。
[Abstract]:Iron was recovered from copper smelting slag by high temperature rapid reduction roasting-magnetic separation process. The effects of basicity of Cao / Sio _ 2, reduction temperature, reduction time and amount of reducing agent on the quality of magnetic separation metal iron powder were systematically studied. The results show that iron in copper slag mainly exists in the form of iron olivine, followed by magnetite, under the conditions of basicity of Cao / Sio _ 2o _ (0.6), coke powder ratio of 12, reduction temperature of 1 300 鈩，
