Abstract: 

Studies on less than 12 mm product due to crushing and sizing plant of Gol-e-Gohar Iron Ore Co. showed that this material contains significant amount of valuable iron ores. Based on the carried out experimental studies, the processing flow sheet designed to upgrade iron content. This plant is known as the first hematite iron ore enrichment plant that has used dry medium intensity magnetic separators (3500 gauss) which are manufactured by Fakoor Sanat Tehran Company. The purpose of the plant is production of fine with iron content mote than 60.5% and recovery by weight more than 55% from the feed with iron content of 54%. In this plant, material at first are classified by a single deck screen (6mm), then screen oversize are separated at one stage by magnetic separator, while screen undersize at two stage. Based on experimental result, a product with iron content of 59.3% and recovery by weight 73% produced.
Practically, the iron content has enhanced by increasing speed of magnetic separators and little decreasing recovery by weight to more than 60.5%. Finally, economical investigations showed that annual proceeds would be 17.8 millions dollar that time of capital return would be 13 day.
