MANGANIFEROUS IRON ORES. - pubs.usgs.gov

2011-11-14  Manganiferous iron ore occurs also in association with the "valley" brown ore in Virginia and Tennessee and with the "Oriskany" brown ore in Virginia. Some deposits or parts of deposits of these ores are highly manganiferous. As in the Blue Ridge deposits, the ores are embedded in residual clay. They have been formed by surface con centration and replacement and do not extend far below the surface. In northwestern Virginia, in the New River region of southwestern Virginia, and in Shady Valley, Tenn., many such deposits are found. Until recently the demand for the ores has been slight, and many deposits have been abandoned. There is little doubt that a large quantity of manganiferous iron ore

Bioflocculation of Egyptian High Manganese Iron Ore

2017-4-19  Although manganese is added into steel for its deoxidizing and desulfurizing properties [3], the occurrence of Mn in the iron ore raw materials causes harm to the reduction process of iron oxides in the blast furnace. Mn forms strong oxides, which are partially reduced in the blast furnace with parts entering the slag.
