Prereduction and magnetic separation of low grade manganese ore
In this study, ferruginous low-grade manganese ore was prereduced by CO, which converted iron oxide to Fe3O4 while manganese oxide was reduced to MnO. Then, the iron-rich component was collected by magnetic separation. The effects of sample particle size and various other reduction parameters on the efficiency of magnetic separation were studied.

Iron Ore Tailings: Characterization and Applications
During the exploitation of iron ore, crushing rocks generates particles of iron oxide, quartz, and clay. Depending on the granulometric classification, the tailings can be classified as fine or coarse waste (granular or sandy tailings). Iron ore with high clay content, for example, tends to generate fine particles.33

This reduces all of the manganese ore to manganese oxide (MnO), which is a leachable form. The ore then travels through a grinding circuit to reduce the particle size of the ore to between 150 and 250 μm, increasing the surface area to aid leaching. The ore is then added to a leach tank of sulfuric acid and ferrous iron (Fe 2+) in a 1.6:1 ratio.
