Mineral and Technological Features of Magnetite–Hematite ...
2021-3-24 Mineralogical studies have established that the main iron-bearing mineral is hematite, which contains 69.02 to 70.35% of iron distributed in the ore. Magnetite and hydrogoethite account for 16.71–17.74 and 8.04–10.50% of the component, respectively; the proportion of iron distributed in gangue minerals and finely dispersed iron hydroxides ...

Extraction of Iron, Iron Mining, Iron Ore Processing
Hematite is easier to floated than magnetic, which could be separated by positive flotation. As the density of iron ore is much higher than that of gangue mineral, gangue mineral is more likely to attach to the foam than iron ore. Therefore, for the extraction of iron ore, reverse flotation is more advantageous than positive flotation.
