| 摘 要： | 为了有效回收炼铁渣中的铁, 对炼铁渣进行三级细磨、二级重选以及一段筛分处理, 制得了MFe含量90%以上的还原铁粉, 实验表明2 t粉铁可制取出1 t还原铁粉, 残渣则可用于制作陶瓷、免烧砖等, 实现了资源综合利用。

| Abstract: | A flowsheet consists of three stages of fine grindings, two stages of gravity separations and a screening process was adopted to recover iron from iron-smelting slag, and reduced iron powder with MFe exceeding 90% can be prepared. The experiment shows that 1 ton of reduced iron powder can be produced from 2 tons of powder iron, while the residual can be used for the manufacturing of ceramic, exempt-burned brick and so forth. |
