The iron ore industry is at the heart of the global decarbonization transformation, with green hydrogen and circular technologies redefining the future of sustainable steel production.

The iron ore industry, a crucial component of the steelmaking value chain, is under considerable pressure to support and achieve decarbonization. 

The industry has made significant progress in reducing Scope 1 (direct) and 2 (indirect) emissions from resources it controls or uses, including vehicles, electricity, heating, and cooling. However, it is still lagging in Scope 3 emissions, which encompass all other indirect emissions, including those upstream and downstream, that occur within the value chain. 

There is no one-size-fits-all solution to addressing the challenges of producing lower-carbon iron ore and steel. A significant shift in technology is currently underway in the steel industry. The question is: What will happen to the industry when the dominant steelmaking technology no longer includes carbon-intensive blast furnaces? Strategies vary depending on several factors, including location, type of ore, and the availability of energy sources. However, a common thread is the need for the industry to innovate and adapt continually.  

North America’s approach 

The North American region produced about 104 million tons of iron ore in 2023, with 60 million tons from Canada and 44 million tons from the United States. The ore in North America, primarily hematite and magnetite, is considered lower grade but responds well to beneficiation, a process that improves the quality of iron ore by removing impurities.  

The main advantage the US has is its ore’s liberation capacity, meaning it can be easily separated during processing but still needs to be beneficiated.  

Beneficiation processes produce high-grade ore that can be used as feedstock, usually in the form of pellets or briquettes, in the traditional direct reduction (DR) process. This results in iron and steel with significantly fewer carbon emissions. However, this process requires significant resources, including water, energy, and consumables, and generates tailings that must be managed appropriately. The average recovery yield is typically 78-82% total ferrous content, while some of the finer iron is lost in the tailings waste.  

In Canada, high-purity iron ore has been recognized as a critical mineral, particularly in the Labrador Trough. This recognition has fostered collaboration between operators, government, and other stakeholders to support the decarbonization of the iron ore and steel industries. Labrador Trough’s high-quality iron ore makes it an ideal candidate for producing DR-grade iron ore, which is essential for greener steel production using existing technology. 

South America’s focus 

In South America, Brazil’s iron ore industry faces similar challenges to those in other regions, including the need to reduce emissions and improve efficiency. Brazil’s orebody has high ferrous content with very low detrimental impurities. This offers a tremendous economic advantage in terms of low-cost production of iron ore and steel. In 2024, Brazil’s overall iron production was approximately 440 million tonnes. However, DR-grade pellets, which are in great demand for their use in environmentally friendly steelmaking, accounted for only 10 to 15% of that production.  

Brazil, therefore, is increasingly focusing on producing high-quality DR-grade pellets to tap into new markets and boost exports by adding beneficiation capacity, as the ROM grade and quality are generally declining. This shift aims to meet the growing demand for these pellets and leverage their economic and environmental benefits. 

Australia’s iron ore landscape 

Australia is the largest exporter of iron ore in the world, exporting roughly one billion tonnes per annum, primarily goethite and hematite from the Pilbara region. The ore is high in gangue (alumina and silica) and ideally suited for the blast furnace route. Due to the unique crystalline structure of the ore, there is currently no commercially viable beneficiation route available to reduce the gangue sufficiently as required for higher-grade ore markets or processes. 

The Pilbara region is home to some of the world’s largest iron ore mines. It accounts for more than 50% of global production. The shipping routes from Australia to Asian are ideally suited for accommodating all the blast furnace production between the continents. Australian iron ore producers are collaborating closely with steel producers in Asia to facilitate the transition to greener, carbon-free technologies. Obviously, as with any producer, it’s essential to stay current with the market. The Pilbara producers are very aware of this and proactively strive to support the transition to carbon-free technology. This includes investing in the development of the direct reduced iron and electric smelting furnace (DRI-ESF) route for higher-gangue Pilbara ores. 

Interestingly, Australia has extensive magnetite reserves, but since goethite is processed easily and there is a large market for it, there is no pressing need to invest in expanding magnetite production. That said, the small amount of magnetite that is mined, both for local consumption and export, has been increasing as global demand for more DR-grade pellets expands.

Exploring alternative energy sources 

Alternative energy sources, such as pyrolytic oil and plasma torches, are being considered to support greener iron ore production. Small modular reactors (SMRs) are also seen as a potential energy source. Despite the complexities involved in their implementation, SMRs could provide a reliable and low-carbon energy source for the iron ore industry. 

The development of new process technologies and innovative solutions is crucial for the future of the iron ore industry. These advancements can help address the challenges of producing high-grade ore and support the decarbonization of the steel value chain. By investing in research and development, the industry can discover new ways to enhance efficiency and minimize environmental impact.
