Removing Sulfur Content In Iron Ore
Removing Sulfur From Iron Ore
The current study is focused on controlling sulfur emissions by pre-treating the iron ore concentrate to remove sulfur by leaching technique. Technically, chemicals are used to react with the sulfur bearing minerals in the iron ore to convert them into a soluble fraction, resulting in an easy separation from the insoluble solid phase.
