It cannot separate iron and steel from nickel and magnetic stainless steels. Also, composite parts containing iron will be collected which could contaminate the melt. Hand sorting may be used in conjunction with magnetic separation to avoid these occurrences. (See Chapter 3 for discussion of magnetic separation techniques).

Furthermore, new steel-making technologies demanded very pure iron ore, purer than the remaining eastern iron deposits could offer. These deposits contained so much rock and debris it was not profitable to turn them into iron ore. However, Edison had an idea. He reasoned that since iron is magnetic, he could use an electromagnet to …

After magnetic separation, the magnetic concentrates consisted almost completely of magnetite (with the magnetization of 75–88 Am2/kg) and non-magnetic residues contained major quartz. The content of iron in magnetic concentrates reached 68.5–70.2 wt.% and iron recovery 77–96 wt.%, depending on size fraction.
