What Is Iron Ore Beneficiation? (with pictures)
9-5-2020 · Low-grade iron ore includes all mixtures below 62% iron concentration, which are not considered to be viable types of ore for use in metallurgy. Several different types of natural iron ore exist, but the two most common types used for metal refining are hematite , Fe 2 O 3 , which is usually 70% iron, and magnetite , Fe 3 O 4 , which is 72% iron.
Beneficiation of Iron Ores – IspatGuru
Low grade iron ores cannot be used as such for the production of iron and steel and need to be upgraded to reduce its gangue content and increase its Fe content. The process adopted to upgrade the Fe content of iron ore is known as iron ore beneficiation (IOB). However, Iron ores from different sources have their own peculiar mineralogical ...
