Mineral and Technological Features of Magnetite–Hematite Ores …

 · The main Fe-bearing mineral in the samples is hematite, which contains 65.09% of the iron in the samples. The share of magnetite and hydrogoethite is 22.86 and 10.17% of iron, respectively. The amount of iron distribution in hematite and magnetite is the same—87.95%. The proportion of iron distributed to other phases is exceptionally low.

Bioreduction of natural specular hematite under flow conditions

 · Here we describe the reduction of specular hematite, a crystalline Fe (III) oxide having a macroscopic platy habit, by the dissimilatory Fe reducing bacterium Shewanella oneidensis MR-1. Our experiments were conducted in the presence and absence of the electron shuttle AQDS using a hydrodynamically-controlled, flow-through reactor.
