Background

After 78 years, ArcelorMittal South Africa (AMSA) officially ceased operations at their Newcastle plant in November 2025.[1] The plant is now under care and maintenance.[2] The closure is a result of ongoing financial issues stemming from energy usage during the BF-BOF process and rail transportation limitations.[1]
