STRATEGIES FOR PROCESSING LOW-GRADE IRON ORE .

Oct 1, 2009 . For example, many ores contain iron oxide in a nonmagnetic form and are so fine-grained that it is uneconomical to grind them to a fine enough size to separate the iron oxides from the gangue. Exploitation of these iron minerals needs to take a different approach, using fewer process steps than are.

Iron ore - Wikipedia

DSO deposits are typically rarer than the magnetite-bearing BIF or other rocks which form its main source or protolith rock, but are considerably cheaper to mine and process as they require less beneficiation due to the higher iron content. However, DSO ores can contain significantly higher concentrations of penalty.
