Iranian president Mahmoud Ahmadinejad has inaugurated the Middle East's largest iron ore pelletizing plant at the southern city of Sirjan, Fars News has reported. The Gol-e-Gohar pelletizing plant has the capacity to produce five million tons of iron ore per year, enough for the production of 2.5 million tonnes of steel. The new plant has been built over four years and will use iron ore concentrates from the Gol-e-Gohar mine in the Kerman province. Approximately $600m has been invested in setting up the factory.
