Highly metamorphosed schistose iron ore from the Marquette range on Michigan's Upper Peninsula has been successfully treated by froth flotation since 1956. The hematite in this ore occurs in the form of specularite, which is more easily beneficiated than the red or dull black hematite typical of oxidized taconites.

As shown in Figure 13.2, minerals with ferromagnetic properties have high susceptibility at low applied field strengths and can therefore be concentrated in low intensity (<~0.3 T) magnetic separators. For low-intensity drum separators (Figure 13.11) used in the iron ore industry, the standard field, for a separator with ferrite-based magnets, is 0.12 T at …

The magnetite beneficiation process The degree to which an iron ore is processed depends mainly on the iron ore products being made. The most common iron ores on the market are lump ore, sinter fines and iron ore pellets/pellet feed. Which products are suitable for a mine is dictated by the ore's liberation characteristics and market demands.
