Bafq-Saghand iron ore region

BAFQ-SAGHAND IRON ORE REGION (RU: Бафк-Сагандский железорудный район) is situated within the central part of Iran, at the distance of 400 kilometres from the Isfahan city to the east. The deposits have been identified and partially explored during the 1965-71 by the collaborative works of the Iranian and Soviet geologists. The deposits of the magnetite ores (Chogart, North Anomaly, Anomaly XI, Saghand, Chadormalu, Se-Chahun-Barbara, Mishdavan, and others) are confined to the contacts of the pre-Cambrian (gneisses, granite-gneisses, crystalline schists, amphibolites) and infra-Cambrian volcanogenic-sedimentary (albitophyres, liparites, and dacites with the interlayers of the chlorite-sericite schists, fine-grained sandstones, and siltstones) rocks with granitoid intrusions. There are distributed along the contact the metasomatites of the actinolite, chlorite, albite, less often scapolite composition, and the calcareous and magnesian skarns in the small quantity. The contact-metasomatic magnetite and hematite-magnetite deposits are situated near the intrusive massifs within the zones of the tectonically-disturbed contact-metasomatic rocks.

The reserves of the magnetite ores of the five deposits of the region are estimated at 700 million tonnes with the average content of Fe of 52.5-56.3%. Part of the ores with apatite component is characterized by the increased content of P (1-2%) and traces of S (0.1 - 0.2%). The largest deposit Chogart is being developed since the 1973 by the open pit method (the open pit mine with the 10-metres benches) with the help of excavators; the transport is the dump trucks. The ore arrives into the crushing plant. The annual extraction of magnetite ore with the content of Fe of 57.6% is 1 million tonnes (1979). The concentrates arrive into the metallurgical plant near the Isfahan city.
