:: Outokumpu's new CIRCORED® Technology for Iron Reduction Boosted by the CAL - ISG Deal  

ISG Venture Inc., a subsidiary of International Steel Group Inc., has announced its agreement to purchase the idled idled Circored® Hot Briquette Iron (HBI) facility in Trinidad and Tobago from Cliffs and Associates Limited (CAL).

The Trinidad and Tobago HBI project began in the mid-1990s as a joint venture between Cleveland Cliffs, Lurgi Metallurgie (now known as Outokumpu Technology GmbH), and LTV Steel. Lurgi Metallurgie developed and delivered the first-of-its-kind Circored® plant for the HBI facility in Trinidad.

The plant is designed to produce 500,000 t/a of HBI using Outokumpu's new fluidized bed based Circored® technology. The process uses natural gas to reduce iron ore fines, significantly decreasing the costs of the steelmaking process due to the elimination of the agglomeration step. The high quality, low cost product can be used as pure scrap substitute in electric arc furnaces as well as for increasing the capacity of existing blast furnaces with corresponding coke savings.

HBI production with Circored® began in 2000 in the first industrial scale plant in Trinidad, but ceased in 2001 due to depressed global HBI prices. Along with increasing steel prices and ISG Venture investing now in the Trinidad HBI production and restarting the plant, Outokumpu Technology sees great possibilities to market the ground-breaking Circored® technology to other steel producers, too, as a highly cost-effective process.
