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. Since
Hydrogen sulfide (H2S) is a dissolved gas that sometimes is found in well water. It is not usually a health risk, but even a tiny amount (0.05 mg/L) can cause the water to smell like rotten eggs, discolor bathroom and kitchen fixtures, corrode metals such as iron, steel, copper, brass, and silver, make food taste and look different, and foul the resin bed of an ion-exchange water softener.
