Weaker iron and steel production in the EU have led to reduced demand for raw materials in the fourth quarter of 2022 and early 2023, particularly for highgrade iron ore and pellets, while coking coal demand was supported by strong energy prices through 2022 and trade restrictions on Russian coal, according to an analysis by SP Global Commodity Insights Jan. 9.

Reducing gases (carbon monoxide and hydrogen) are used to remove the oxygen from the iron ore, resulting in a highly metallised iron product in pellet or lump form (depending on the type of iron ore feedstock, pellets or lumpy ore). The resulting DRI product is very porous in nature and as a result is highly reactive with a tendency to reoxidise.

During the handling of DRI products, breakage and spillage can account for significant losses of product. Handling losses can exceed the impact of total iron content or gangue content on the total yield from iron ore to liquid steel. However, handling losses often are absorbed by different operating areas and are not accounted for in total.
