Circored and Circofer processes of ironmaking IspatGuru

Both the Circored and the Circofer processes have been developed by Lurgi Metallurgie GmbH, Germany (now Outotec Oyj, Finland) for the production of direct reduced iron (DRI) from iron ore fines. For both processes, capacities above 1 million tons per annum are possible in a single production unit, resulting in improved economies of scale.

Pumping Iron at Cliffs Associates The Circored Iron Ore

The basic chemical reaction underlying the Circored process relies on an addition of hydrogen to the iron ore, which reacts to pure iron and water (Fe2O3 + 3H2 → 2Fe + 3H2O). A process engineering diagram is shown in Exhibit 4, which is further simplified to a conventional process flow diagram, as shown in Exhibit 5.

Understanding the Supply Process: Evaluating Process Capacity

The Circored plant converts iron ore (in the form of iron ore fines) into direct reduced iron (DRI) briquettes. Iron ore fines are shipped to the plant from mines in South America; the briquettes the process produces are shipped to various steel mills in the United States. The example of the Circored process is particularly useful for our purposes in this chapter.

Blog: Is it time for China to switch to electric arc

In 2017, China’s steel scrap exports suddenly surged to reach 2.3 Mt, which triggered a debate over whether or not China should build more electric arc furnace (EAF) plants to make use of its increasing domestic steel scrap. Today, EAF technology represents around 6.5% of China’s steel production, compared to around 45% elsewhere in the world.
