medium gangue ore concentrate in Osaka Japan East Asia
If theganguemineral in an ironoreis predominantly quartz, reverse flotation is usually used in the cleaning stage to improve theconcentrategrade. Figure 9.13 presents a typical flow sheet for processing an oxidized ironorecontaining about 30% Fe using a combination of SLon magnetite separators and reverse flotation. Theoreis mainly composed of magnetite, hematite, martite, and quartz.
