The pH dependence of kaolinite flotation is also opposite to that of silica, which explains why it is difficult to remove kaolinite in iron ore flotation[29]. For depressant-kaolinite interactions, it was found that selective depression of hematite against kaolinite largely depends on strict pH control in iron ore flotation circuits and the level of ionic strength in iron ore flotation pulp.

Iron Ore Statistics and Information - usgs.gov

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world's iron and steel industries.
