Iron Sulfide (II): Properties, Risks and Uses

In the purification of crude phosphoric acid, iron sulfide is used as a reducing agent to remove the heavy impurities of phosphoric acid. Another use of iron sulphide is in the production of malleable iron. Iron sulphide combined with ferrous silicon and ferromanganese is used to increase the sulfur content of steel and iron.
