Sulfuric Acid Production from Iron Pyrite

Sulfuric Acid Production Cost Breakup from Iron Pyrite

This report presents the economics of sulphuric acid production from iron pyrite. In this industrial process, gas produced from the heating of iron pyrite (iron sulfide) is first treated to purify and isolate sulfur dioxide (SO2). This gas typically contains impurities that are removed to increase the efficiency of the subsequent steps. Once purified, the sulfur dioxide is then converted into sulfur trioxide (SO3) through a catalytic oxidation process. This conversion is typically facilitated by a catalyst such as vanadium pentoxide (V2O5) at high temperatures. The sulfur trioxide produced is a key intermediate used in the manufacture of sulfuric acid.
