Michigan Technological University is developing an integrated system of technologies to recover the iron value from BOF steelmaking slag. It will also divert the residual non-iron bearing fraction into a feedstock for the manufacture of acid mine drainage (AMD) neutralizing agent. In this project, technologies are being developed to separate iron from the BOF slag and prepare those iron units for furnace charge.

No proven, commercially viable results are available from these initiatives.  In countries like China and India, slag can be used more easily for road construction and other similar projects.
