Head of Board of Directors of Aluminum Industries Syndicate Houshang Goudarzi said that the figure was 2,000 tons higher than the target set in the said period, Fars News Agency reported.
"In all, 188,956 tons of alumina powder, 112,708 tons of lime, and 321,225 tons of aluminum hydrate were produced in the country in over past nine months," Goudarzi added.
Iran is among the tenth mineral-rich countries in the world, and is resolved not to trade in raw materials, rather it has planned to process the minerals to earn more value-added from exports.
In a relevant development in March 2015, Iranian investors and a Chinese company agreed on the construction of a large aluminum complex in the southern province of Fars.
Project Director Mohammad Mahdavi said the Iranian Mines and Mining Industries Development and Renovation Organization (IMIDRO) and Qadir Investment Company have provided funds for the projects.
He added that the Chinese NFC Company will implement the project.
Mahdavi said that the aluminum complex, with an annual production capacity of 300,000 tons, is to be established in Lamerd Special Zone, Fars Province, within three years.
Iran is currently China's third largest supplier of crude, providing Beijing with roughly 12 percent of its total annual oil consumption.
