WhatsApp: +86 188380728291. Introduction. The processing and utilization of iron ores are intimately linked to their mineralogical characteristics, liberation pattern, and the nature of inclusion of the impurities such as SiO 2, Al 2 O 3, P and goethitic, oolitic and wad type ores containing high silica and alumina are very difficult to process by conventional beneficiation techniques.
WhatsApp: +86 18838072829The iron (Fe) content of such ores ranges from 72% to 35%. The highly friable and fully liberated constituents in ore, such as alumina and silica, generate a large quantity of fines during mechanized mining and crushing. Fine gangue material or iron ore slimes having <45%55% Fe are discarded as reject during the ore beneficiation process.
