Digestion of Alumina from Non-Magnetic Material

Recovery of iron from iron-rich diasporic bauxite ore via reductive roasting followed by magnetic separation has been explored recently. However, the efficiency of alumina extraction in the non-magnetic materials is absent. In this paper, a further study on the digestion of alumina by the Bayer process from non-magnetic material obtained after magnetic separation of reduced iron-rich diasporic ...

Iron cross first class, non-magnetic core - Axis History Forum

2009-10-11  Post. by tommy303 » 09 Apr 2007, 21:02. As an addendum, it does not hurt to be suspicious, as the 1939 Iron Cross was highly standardized by the LDO. Original vaulted or convex crosses are known, as well as ones with non magnetic centres, and may have been early production before standards were tightened up.
