E-Iron International
The E-Iron™ process incorporates a patented portfolio of more than 30 E-Iron™ nugget patents and E-Iron™ nugget furnace patents. The E-Iron™ process is a low carbon footprint technology that produces high quality, 95-96% iron, 2-3% carbon, low sulfur pig iron grade iron nuggets using environmentally benign organic biomass as the reductant in the place of coke or coal.
An E-Iron plant has two pathways to produce zero carbon emission pig iron. One pathway uses an electricity heated tunnel furnace, including a microwave heating system. The second pathway uses a natural gas fired tunnel furnace that includes a Clearite plant to capture and remove the carbon emissions.
Our Features
01
Reduce CO2
E-Iron™ Furnace with biomass produces 0.27
tonnes CO 2 per tonnes of pig iron. A CO2
reduction of 85% compared to the blast furnace. The blast furnace produces 1.8 tonnes of CO2 per tonne of pig iron.

02
Reusable Waste
E-Iron™ can convert iron bearing steel mill
waste products or low cost, mid-grade iron ore concentrates into pig iron grade iron nodules with a market value of $450-$500/tonne. High-quality, low-cost E-Iron™ can be used alone or blended with scrap iron in steel making and iron foundry operations.
03
Replacing Coal
The plant will use the E-Iron™ Process with biomass, i.e. hardwood, softwood, or bamboo, as the reductant in the place of coal. E-Iron plans to collaborate with iron ore producers to supply self reducing (biomass reductant) pellets as feedstock to the “mini-iron nodule plants”.
04
Proven Process
The E-Iron™ process proved out with the successful completion of an extensive and successful pilot plant program, preceded by considerable laboratory and small-scale testing. High quality iron nodules were produced on a 24-hour per day schedule in a linear furnace owned by Tundra Industries, near Minneapolis, Minnesota on three different iron ore concentrates and three different types
of biomass.
E-Iron nuggets can be produced from self producing briquettes or in the loose, unagglomerated form. The loose mixture eliminates the cost of briquetting and produces larger iron nuggets.
