Hot Briquetted iron

Ironstone's hot briquetted iron is designed to address the needs of today's steel industry seeking metallics to reduce its energy intensity and carbon footprint.

HBI is a premium quality, high density raw material containing 90-94% total iron (Fe), used in electric arc furnace (EAF) and basic oxygen furnace (BOF) steelmaking, blast furnace (BF) iron making, and foundry applications. It is essentially a compacted form of Direct Reduced Iron (DRI) designed to facilitate easy shipping, handling, and storage.

Ironstone is targeting annual production of 2.5 million tonnes of high quality, high value hot briquetted iron (HBI) suitable for sale to traditional steelmakers and those employing modern electric arc furnaces in addition to the North American scrap industry as alternative iron units.

Approximately 9 millions tonnes of ore will be mined from Ironstone's Clear Hills deposit annually. With a current NI 43-101 indicated resource of 557 million tonnes, this represents over 60 years of mine life.

In the worldwide steel industry, few segments are as closely linked as Electric Arc Furnace (EAF) steelmaking and the direct reduction of iron ore. The past 40 years have seen a major rise in EAF steel production and a corresponding dramatic growth in the global use of Direct Reduced Iron (DRI). It is common for EAF’s to rely heavily on DRI as a primary feedstock or as a supplement to scrap metal.

There is a continuing need for new, efficient, economic, environmentally-friendly metallics capacity. However, premium metallics are getting harder to source and prices are increasing due to tightening scrap availability and supply constraints in traditional exporting nations including Brazil, Russia and Venezuela.

The world of DRI is growing and the steel industry is looking to use it to its full potential in the upcoming years.  

Advantages of HBI


  • High bulk density of 2500-3300 kg/m3
  • Known, consistent chemistry certified by producer
  • Minimal (trace) amounts of undersirable chemical elements (Cu, Ni, Cr, Mo, Sn, Pb, and V)
  • High thermal conductivity
  • Low reactivity with fresh and saltwater (reoxidation)
  • Resistant to degredation due to handling and weathering
  • Compatible with all bulk materials handling equipment
  • Safe and easy to store and ship
