    Hematite Homojunctions Without Foreign Element Doping For ..

    Abstract. This enables us to fabricate hematite homojunction photoelectrodes without foreign element doping by constructing bilayer films with different Fermi levels, and realize enhanced photoelectric conversion efficiency for highly efficient solar water splitting. The photocurrent density for the hematite homojunction is ∼1.1 mA cm −2

    Usually, any type of iron ore is processed first to get rid of all its impurities before it is fed into the blast furnace for conversion into iron, but because the concentration of iron in hematite is so high, it can be added to the furnace directly without processing it first.

    The way a given ore is described in terms of the enrichment. The higher the concentration factor, the richer the ore, and the less of it needs to be mined to extract a given amount of the metal. In General, the minimum concentration factor required for profitable mining is inversely porportional to the average crustal concentration

    The hard hematite ore bodies with66 wt% Fe contain microplaty hematite and occur mainly near the contact with the underlying metavolcanic rocks, where they are surrounded by an aureole of hydrothermal carbonate alteration. Relict BIF bedding is generally preserved in the hard ore, with dense hematite alternating with porous hematite.
