11/2/2020, · The company is piloting a hydrogen-based ,ironmaking, process (HYBRIT) which, if successful, could drastically reduce the carbon footprint of its operations: one pilot ,plant, is to start up in 2020. SSAB's plan to convert its blast furnaces to EAFs using the HYBRIT technology by 2040 would likely involve an expensive transition and thus supportive policies.

Beneficiation processes of iron ore generate dust in the atmosphere, acid mine drainage in the ecosystem and metallic iron for steelmaking. Beneficiation process requires dissolution of minerals surrounding the ore and the release of metals and cement matrix into water courses. These generates acid leading to acid mine drainage.
