Sirjan Iron Ore Complex

Saeed Pirmoradi, Managing Director

Gol Gohar Region

Gol Gohar mineral zone with rich iron ore mines is one of the most active mineral-industrial poles in the Middle East, having ample capabilities to become a large and competitive region in Iran and even in the world. These mineral reserves are located 50 km southwest of the city of Sirjan. The existing works and the remaining drillings in the place of the deposit indicate that this mineral zone has been identified and explored in the past centuries.

The approximate age of a sample of the slag of the old furnaces of Gol Gohar Mine has been estimated at about 900 years. Gol Gohar iron ore deposit in six distinct anomalies (enabled) with total reserve of over 1200 million tons, has been located in an area with an approximate length of 10 km and width of 4 km.

With regard to the importance of Gol Gohar region at the national level as the country’s iron pole and also the position of the region which is the closest mineral zone to the Persian Gulf waters, in a near future it will possess the process of iron ore extraction to production of steel parts. Also, with respect to future macro production plans, the employed manpower in the region will be about 20 thousand people directly and close to 60 thousand people indirectly in the entire region by that date.

Sirjan Iron Ore Complex

Sirjan Iron Ore Complex is among the prestigious and large complexes of the country. It started its operation in the calendar year 1387 (2008/2009) within the framework of equipping Gol Gohar 2 and 4 mines in the field of iron ore extraction.

This complex, up to the month of Esfand 1394 (February/March 2015/2016) managed extraction operations from the mines directly and by employing the contractor. With regard to the communicated upstream rules and policies of the Iranian Mines and Mining Industries Development and Renovation Organization (IMIDRO), in the above-mentioned date Gol Gohar Mine 4 was ceded to a partnership between IMIDRO and the private sector through receiving due share.

It is now directly administering extraction of Gol Gohar Mine 2 by using a contractor and on behalf of the Iranian Mines and Mining Industries Development and Renovation Organization (IMIDRO) and Iran Mineral Production and Supply Company, is supervising over mines 1, 3, 4, 5, and 6.

It should be noted that in line with the enforcement of the communicated upstream rules and policies, the Iranian Mines and Mining Industries Development and Renovation Organization plans to share Gol Gohar Mine 2 with the private sector through receiving the due share and by holding public sale. Therefore, in future, Sirjan Iron Ore Complex will supervise over all he mines in Gol Gohar area on behalf of IMIDRO.

Currently about 500 people are working at Sirjan Iron Ore Complex in the position of employers, supervisors and contractors. Due to the importance of Gol Gohar region at the national level as the iron pole of the country as well as the position of the region that is the closest mineral region to the Persian Gulf waters in a near future it will hold possession of the process of extracting iron ore up to the production of steel parts. Also with regard to macro production plans in future, the employed manpower in the region up to that time will be about 20 thousand people directly and close to 60 thousand people indirectly in the entire region.

Gol Gohar Mine 2

Gol Gohar anomaly 2 is one of the six identified reserves in the Gol Gohar zone. Exploration operations in Gol Gohar 2 mass have taken place during stage 1 in a regular network with a length of 1400 meters and width of 550 meters and with the drilling of 41 exploratory wells which have been conducted within 100 meters from each other. Some 7446 meters of drilling have been done on the mass in this phase. Meanwhile, 3150 meters of exploratory drilling was conducted during the second phase in the calendar year 1385 (2006/2007). The third phase of the exploratory drillings which began in the month of Khordad (June/July) 1390 (2011/2012) with the drilling of 12 wells and a total of 1422 meters of drilling, ended in the month of Azar (November/December) the same year. In total, up to the end of phase 3, some 12018 meters of exploratory drillings were conducted within mine 2 precinct. The last phase of the exploratory drillings started in the calendar year 1391(2012/2013) with the drilling of 86 wells in an area of 15900 meters. On this basis, the total exploratory drillings on this mass from the beginning up to the end is more than 27915 meters.

Based on the explorations conducted up to date, the amount of geological reserves of the mine has been estimated at 59 million tons of iron ore which, in comparison to the reserves estimated at the end of phase 2, it has increased by about 7 million tons. Based on the latest mine extraction plan conducted at the end of phase 2 of the explorations, 48 million tons of iron ore reserves with a stripping ratio of approximately 3 to 1 can be extracted.

In the final plan of the extraction, operations from the initial surface of the ground (approximate height of 1745) have been started and will continue up to the balance of 1530 (the approximate mine depth of 215 m). At the end of the extraction operations with connection of every 2 stairs with a height of 15 meters, the height of the final stairs of the mine will reach 30 meters (a total 14 stairs of 15 meters height will be turned into 7 stairs of 30 meters).

The length and width of the mine at the end of its life will reach 1680 and 998 meters respectively. The slope of the working stairs of the mine in normal condition and for the stone walls has been considered at 60° and for the alluvium 45°. The final slope in the mine walls in the alluvium part has been considered equal to 38 and in the stone section is 45 degrees. In the life course of the mine usually a safety stair in each horizon is considered. On this basis, the width of the safety stair for soil and stone stairs with a height of 30 meters has been considered 10 meters. Under the current condition and with the existing machineries, the working stairs in the tailing and alluvium has a height of 15 meters.

Extraction operations of Gol Gohar Mine 2 started on October 28, 2005. At present extraction operations are concentrated on the central and southern parts of the mine and the deepest part of the mine is balanced at 1605. In 1395 (2016/2017) about 2.93 million tons of tailings and about 1.12 million tons of iron ore were extracted from Gol Gohar Mine 2. The useful life of the mine is almost 19 years.
