Mo i Rana


The plant was founded in 1955 as a part of A/S Norsk Jernverk. The plant was producing pig iron and the owner was the Norwegian state. In 1989 the plant became a part of the private sector and since then the company has had 5 different private owners, and the production has changed from pig iron to ferroalloys. In 2018 we became a part of Ferroglobe. Currently the plant is producing Ferromanganese in two furnaces.

At site there is also a Sinter plant.

Ferroglobe Mangan Norge AS has a strong commitment to HSE, and internal and external working environment is a priority area. The company is always working on improvement and is certified in ISO 9001, 45001 and 14001.
