Project Outline
As a raw material, Iron ore does not have considerable added
value by itself. Thus processing and producing of pellet and sponge iron and
finally its conversion into steel not only creates job opportunities but also
supplies the producers with a rather higher added value. Continuous growth of
steel production in the country highlights the ever increasing need for
establishing pelletizing units. Golgohar Mining and Industrial Co. accordingly
decided to construct a pellet producing plant, following the construction of an
iron ore concentration plant.
This plant is capable of producing high quality
pellets which are usable in Direct Reduction (DR) furnaces. It will also
manufacture pellets with suitable and desired quality which can be fed directly
into blast furnaces.
Procedures of Pellet Production
Golgohar pelletizing unit
will be constructed in Sirjan by Golgohar iron ore company with production
capacity of 5 million tonnes per year. Through a 470 meters long conveyor belt,
Golgohar's concentrated outputs are transported to primary storage tanks, each
with the capacity of 2000 tonnes. One of the reservoirs is dedicated to hematite
ore. Producing pellet consists of three main stages:
- Preparing the material that
includes drying, milling, separating small and large particle, storing in
storage pits and mixing
- Producing raw pellet by means of rotary drums
pelletizers
- Indurating, screening and transporting for maintenance or
distribution
Scope of Work
- Geotechnical studies
- Site preparation
- Performing
detailed engineering design based on Outotec’s basic designs (these activities
are carried out by Sepahan Beyond Research Company)
- Procurement and
transportation of equipment, steel structures, mechanical, piping, electrical &
instrumentation (this part is related to items which are not Outotec Company´s
responsibilities)
- Execution and installation of all equipment
- Precommissioning
and commissioning
