济钢粗颗粒污泥采用一级磨矿＋磁选重选工艺提取活性铁粉，由于原料成分波动大，选别一直无法达到预想效果，通过对现有工艺进行分析，改进采用磁选＋重选＋摇选组合式选别工艺，使粗颗粒污泥选别活性铁粉达到了设计要求，得到了活性铁粉品位88%以上、全铁92%以上的活性铁粉，并实现了产线的连续稳定运行。
濟鋼粗顆粒汙泥採用一級磨礦＋磁選重選工藝提取活性鐵粉，由于原料成分波動大，選彆一直無法達到預想效果，通過對現有工藝進行分析，改進採用磁選＋重選＋搖選組閤式選彆工藝，使粗顆粒汙泥選彆活性鐵粉達到瞭設計要求，得到瞭活性鐵粉品位88%以上、全鐵92%以上的活性鐵粉，併實現瞭產線的連續穩定運行。

Active iron powder was extracted from Jinan Steel’s coarse granular sludge by first grinding + magnetic gravity beneficiation process. Because of large fluctuation in the chemical composition of raw materials, the concentrating process can not be to achieve desired effect. Through the analysis of existing processes and implementing the combination process included magnetic dressing+gravity concentration+shaker dressing, active iron powder with 88%above grade and 92%above TFe was got, realizing continuous and stable operation of the production line.
