Decarbonizing ferrochrome: Reflections from Samancor Chrome

As part of the Industrial Decarbonization Analysis, Benchmarking, and Action (INDABA) Partnership’s recent study tour, our team visited Samancor Chrome’s Ferrometals operation in Emalahleni, South Africa. The visit offered a close-up view of an industry that is essential to stainless steel production, deeply embedded in South Africa’s industrial history, and has long been considered exceptionally difficult to decarbonize.
Ferrochrome production is energy- and carbon-intensive by design. Chromite ore is upgraded through pelletizing, sintering, and submerged arc furnace smelting to produce ferrochrome, which supplies chromium units needed for stainless steel. At Samancor, we saw the full production chain: raw material receiving and storage, pelletizing and sintering, smelting, tapping, casting, crushing, metal recovery, and dispatch.
We also had the chance to watch a furnace tap, which was spectacular. The intensity of the heat, the flow of molten ferrochrome and slag, and the precision required to manage the process, often with a human hand, were a vivid reminder that industrial decarbonization is not an abstraction. It happens in facilities where people manage complex, high-temperature processes under demanding operating conditions.
Our visit to Samancor underscored why heavy industry transitions must be grounded in operational reality. The path to producing ferrochrome with lower carbon dioxide emissions intensity will be challenging—but understanding the process, the people, and the constraints involved is the first step toward identifying solutions that can work.
