allmineral 5 | Iron ore mining and beneficiation Iron ore mining and beneficiation • Mining of high grade deposits • Selective mining of high grade areas and dumping of low grade ores • A lot of small capacity mines and few high capacity mines In the past Today • Ratio of high grade/low grade in the deposits is coming down • The specific value of % Fe in saleable product
What is beneficiation of iron ore? Iron is found that the earliest in the world the most widely used the dosage is most its consumption accounts for about 95% of total consumption of metal Smelting iron ore is mainly used in iron and steel industry carbon content of different cast iron (carbon content is commonly 2% above) and steel (carbon content is commonly below 2%)
iron ore (+63% Fe) is required Besides that around 100 Mt of quality ore is expected to be exported All together 270 Mt of prepared quality ore is required which corresponds to mining of around 400 Mt of run-off-mine (ROM) ore every year It has been estimated that at
Iron ore is beneficiated by crushing and then separating the iron from the gangue minerals through screening This is usually so efficient that lower grade ore can be treated especially when the magnetite is quite coarse Common iron ore crushers are jaw crusher cone crusher and fine jaw crusher
