Tunnel sponge iron reduction unit

Tunnel sponge iron reduction unit (the first anthracite-based pellet softener):

Construction and operation of a sponge iron production plant by tunnel kiln method with a nominal production capacity of 70,000 tons, the project of which started in June 1996. In practice, the "scrap" feed produces induction units and an electric arc.

Production of 140 to 160 kg sponge tubes of the product, which is used in induction furnaces, is produced for the first time. In this project, 125 billion Tomans have been invested, which in its kind has various features, including:

Flexibility in receiving input load (pellet soft, oxide shell, concentrate, etc.)
Production of low carbon product for induction melting units
5% optimization of energy consumption and production slag during melting compared to other forms of sponge iron
No need to bribe the product and the possibility of direct consumption in smelting
Possibility of more storage and transportation and reduction of oxidation risks of the product compared to Midrex sponge iron
Ability to produce products with a total iron content of 90 to 98% with metallization of 96% and above.
Possibility of feed production of metallurgical powder production units

We are proud to announce that this company has the ability and technical knowledge to design, manufacture, supply and install concentrate production plants as well as tunnel sponge regeneration.

It is worth mentioning that the employment rate in the hematite recovery plant is 250 people directly and 600 indirectly and also the employment rate in the tunnel recovery factory is 150 people directly and 350 people indirectly.

Hematite recovery unit (the largest hematite factory in the country):

Hematite recovery plant with investment in the form of BOO contract with the support of Gol Gohar Mining and Industrial Company in the form of investment of 6.4 million Euros and 2600 billion Rials in a period of 23 months with the help of Izad Manan portal and potential experience and scientific ability of regional personnel Gol Gohar was put into operation and is known as the largest hematite factory in the country.

The hematite unit consists of 2 dry feed recovery lines with a capacity of 600,000 tons per year and 2 wet feed recovery lines with a capacity of 400,000 tons per year.

Distinctive features of hematite unit:

8-year independence of feed supply to the mine and iron ore due to the benefit of low-grade intermediate feed
Complete the product value chain by diluting low-grade hematite intermediates
Utilizing the local knowledge and capital of Gol Gohar region in design, implementation, installation and operation
Feed capacity 4 million tons per year
Production capacity of 1 million tons of concentrate per year (up to 1.6 million tons)
Product concentrate with 65% iron grade
Product grain size below 100 microns
Production of hematite pellet feed (qualitative and quantitative enhancer of pelletizing)
Technology: Includes gravity separation steps, milling up to 75 microns, high intensity magnetic separation, sulfur flotation and filtration.
EPC Contractor: Goharroosh Sirjan Company, which has used the power of Ronak Engineering Consulting Company in the design process.
Flexibility in feed including hematite and magnetite granulation rocks

vision :

Becoming the largest productive investor and entrepreneur in Gol Gohar region by 1404 with the aim of promoting creative industrial development, complementing the value chain of the mining industry and creating continuous employment


Creating added value in areas with high-yield and industrial potential along with scientific management and localization of knowledge and equipment using the financial and technical capacity of the largest operating companies in Gol Gohar region
