If the gangue mineral in an iron ore is predominantly quartz, reverse flotation is usually used in the cleaning stage to improve the concentrate grade. Figure 9.13 presents a typical flow sheet for processing an oxidized iron ore containing about 30% Fe using a combination of SLon magnetite separators and reverse flotation. The ore is mainly composed of magnetite, hematite, martite, and quartz.
