Mesabi Metallics has announced plans for a $15bn steel complex in Iowa, linking new direct-reduced iron and electric arc furnace capacity with its iron ore mine in Minnesota. According to American Recycler, the company presented the proposal at the White House as part of an $18bn investment programme, including $3bn being spent to complete the Minnesota mine.
The Iowa development is planned for Lee County, but important conditions remain outstanding before construction can start. American Recycler reported that the precise site had not been publicly finalised, while local records showed neither a completed land purchase nor a final site plan. Permitting remains at a preliminary stage, and Iowa lawmakers are considering changes to the state’s tax-incentive programme to accommodate an investment of this size. Some financial arrangements also remain unresolved.
The proposed supply chain would start at Mesabi’s mine in Nashwauk, on Minnesota’s Mesabi Iron Range. The operation will produce Patriot Pellet, a direct-reduction-grade iron ore pellet intended for modern EAF-based steelmaking. American Recycler described the mine as the first new US iron ore mine built in 50 years. More than 1,500 construction workers and over 200 full-time employees are already working there, with the permanent workforce expected to reach 350 when the mine is fully operational.
Pellets from Minnesota would supply the Iowa complex, which is planned to combine hot DRI with EAF steelmaking. Mesabi says the technology would substantially reduce energy consumption and emissions, although the report provides no quantified savings. The company’s stated aim is to establish a domestic production chain covering mining, melting and pouring, rather than relying on imported iron alongside the scrap used by US electric furnace producers.
Chief executive Joe Broking said the investment would support US manufacturing and supply steel for defence, vehicles, shipbuilding, appliances, energy and infrastructure. Mesabi also expects employment and wider economic benefits across Iowa and Minnesota. Those ambitions remain dependent on advancing the project beyond its announcement: American Recycler highlighted continuing concerns over the site commitment, necessary legislative changes and local communities’ readiness to accommodate the development.
