9 - Developments in the physical separation of iron ore
Because the crystal water in limonitic ores will report to the iron ore concentrate in magnetic separation, the iron ore concentrate grade is limited to about 52% Fe. Figure 9.17 shows an example of a flow sheet to upgrade a limonitic ore. The ore is mainly composed of limonite and quartz with a grade of about 40% Fe.
