Rio Tinto and China Baowu have successfully concluded industrial-scale trials using Pilbara Blend iron ore in hydrogen-based shaft furnace processes. Conducted at Baowu’s Zhanjiang Steel Operations, the testing confirms that mid-grade iron ore from Western Australia can be effectively utilized as feedstock for direct reduced iron (DRI) production. This breakthrough marks a significant step in the companies’ ongoing partnership to decarbonize the global steel value chain and offers a viable pathway for utilizing lower-grade ores in greener steelmaking technologies.
Expanding Feedstock for Green Steel
ta-path-to-node=”0″>Current hydrogen-based direct reduction processes typically rely on high-grade iron ore; however, this material is increasingly scarce and expensive. By proving that Pilbara Blend—a staple mid-grade product—can be successfully processed into DRI, Rio Tinto and Baowu are effectively addressing one of the primary constraints in the energy transition for heavy industry. Furthermore, the trials involved using pellets containing one-third Pilbara Blend. Subsequently, this material underwent processing in a basic oxygen furnace. Finally, the team conducted further testing in a 500kg electric smelting furnace to ensure the resulting steel met necessary quality standards.
Strengthening Industrial Partnerships
This initiative follows a 2023 memorandum of understanding (MoU) between the two firms specifically targeting decarbonization. The success of these trials underscores the depth of a long-standing technical collaboration that spans over half a century. For the steel industry, this outcome provides a clear signal that process innovation can help bridge the gap between current blast furnace operations and the future of low-carbon, hydrogen-fueled electric smelting.

SuperMetalPrice Commentary:
This trial is a crucial technical milestone for the iron ore sector, as it de-risks the future for mid-grade ore producers. If this technology reaches widespread commercial adoption, it will significantly alleviate supply-side pressure on high-grade hematite deposits and solidify the position of Australian producers in a decarbonizing steel market.
