Direct reduced iron is produced by the reduction of iron ore by carbon monoxide and hydrogen, as illustrated in simplified form in the equations below: Fe 2O 3 + 3CO → 2Fe + 3CO 2. Fe 2O 3 + 3H 2 → 2Fe + 3H 2O . There are several processes for direct reduction of iron ore, principally gas-based shaft furnacesWeb

The ores are removed from storage by bridge scrapers or retainers. Scraper chains push the ores lengthways onto conveyors belt that run parallel to the ore stockpile. The removal from the front is done by rakes with small lateral movements. The ore begins to slide and scraper chains pick up the bulk material and transport it onto conveyor belts.Web
As the buffer area for temporary storage of iron ore, stockyards of iron ore terminals often emerge as the bottlenecks in the entire transportation process. ... Storage space management in bulk terminals has become an important focus for research and practical operation due to the increasing demand for bulk cargo and limited storage …Web
Ore car dumping Once the train arrives at the port the ore cars go through the car-dumper. The ore cars are rotated and the ore flows out into bins and then is discharged onto conveyors. Stockpile The ore is stockpiled according to product type and the quality control plan. The travelling stackers create 250m long stockpiles. Rotary bucket-wheelWeb
Iron Ore Fines (IOF) are a product of iron ore, commonly having a particle size less than 6.3 mm, which is transported around the world in bulk carriers. Since the holds of bulk carriers are not designed to carry liquid, if liquefaction of IOF or other minerals occurs, it can cause the vessel carrying the cargo to list or even capsize.Web
Use of automatic fire extinguishers and emergency response procedures not only minimizes the possibility of life threat, but also protect iron ore from spoiling. …Web
To verify this procedure the TWG measured the bulk density of IOF in the holds of multiple bulk carriers, before and after transportation, through means of height measurements, laser scanning and cone penetration testing (Iron Ore Technical Working Group, 2013a, Iron Ore Technical Working Group, 2013b).Web
For many years, the Machinery Division of Dravo Corporation has been designing and constructing bins and bunkers as part of overall plant facilities. We have designed bins to handle a variety of materials including coal, coke, iron ores and concentrates, sintered and pelletized ores, calcined and raw limestone, bentonite, alloys …Web
Based on the particle size, iron ores are classified as iron ore fines (<10 mm) or iron ore lump (6.3–31.5 mm); iron ore fines are first processed in a sinter plant, while lump ores can be charged into the blast furnace (BF) directly. Iron ore lump is the lowest cost iron bearing material for the BF burden.Web
