  • Enrichment of Fe‐Containing Phases and Recovery of Iron

    Jan 13, 2012· Steel slag normally contains a large amount of iron and its oxides. Therefore, it is a potential renewable resource in case of inadequate iron ore supply. To recover the metals from steel slag, two types of BOF slags were remelted at 1873 K.

  • An overview of recovery of metals from slags ScienceDirect

    Jan 01, 2003· Therefore, the basicity of AOD slag is lower than steel slag. Moreover, AOD slag contains much less iron than steel slag. Hence recovery of iron from AOD slag is not important. Perhaps the most important characteristic of AOD slag is that it contains a high amount of Cr (2.5–4.3%) and some Ni (0.2–0.45%).

  • Optimization of magnetic separation process for iron

    Three types of slags, namely basic oxygen furnace slag, desulfurization slag, and iron ladle slag, were studied, and the results showed that the optimized recovery efficiencies were 93. 20%, 92. 48%, and 85. 82% respectively, and the recycling efficiencies were improved by 9.
