About the Team

ArcelorMittal Liberia (AML) is operating inside Liberia since 2006, where we are employing approximately 1600 employees and about 1000 contractors mainly in the area of security as well as in transactional manual work like Bush cutting keeping the railway and our concession area free of natural overgrowth, as well as putting tarpaulins on the railcars etc.

In Liberia we are running operations, spread over three locations, our harbour, and our Main offices in Buchanan, and the Nimba region the mines, existing of multiple mining locations at Tokadeh, Gangar and Yuelliton and a Crushing plant and rail loading facility, serviced by our own accommodation settlement in Yekepa.

These locations are all connected with a 260 km Railroad, operated, and managed by AML, as per the MDA between ArcelorMittal and the government of Liberia.

Currently 5 mtpa iron ore (DSO -Direct Shipping Ore) are produced, which will be phased out in the next few years and replaced with Iron Ore Concentrate. The Phase 2 project aims to increase export of Iron Ore to 15 mtpa (concentrate). This was restarted end 2020 after it was put on hold in 2014 due to Ebola outbreak in. Significant civil construction work was already well advanced when the project was put on hold. Phase 2 of the project consist of an iron ore concentrator at the mine, rehabilitation and upgrade of Rail line, and a new iron ore bulk handling terminal in the port.
