Gravity separation . Froth floatation method . Electromagnetic separation . Leaching method . Gravity separation, froth floatation and electromagnetic separation methods are physical methods while leaching method is a chemical method of concentration of ores. Gravity separation It is based on the difference in the weight of metal and matrix. 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,
