Production capacity has been increased from 2 million tonnes to 3.5 million tonnes in 2008. production was of 3.25 million tonnes in 2008.

ERAMET is the world leader in refined manganese alloys, which have high added-value, strenghening this position with the acquisition of Tinfos in July 2008 at 56 %, then 100 % in 2009.

April 7th, 2009 : The first stone was laid at the future Metallurgical Complex of COMILOG, a 67%-held ERAMET subsidiary based in Moanda (Gabon). The project consists of a silicomanganese plant with 65,000 ton annual capacity and a 20,000 ton per year manganese metal plant. The Complex will benefit from the Gabonese government's development of a new hydroelectric plant as part of the upgrading of the national electricity grid. Capital expenditure for the Moanda Metallurgical Complex will total €200 million, spread over the 2009-2013 period ; if all the required conditions are met.

Eramet Manganese started up a new Chinese plant at Chongzuo, in January 2007, for production of electrolytic manganese dioxide for Chinese manufacturers of alkaline batteries. The capacity of this plant has recently been doubled.

The branch has a network of 19 industrial sites on four continents (Africa, Asia, Europe, America). 

This concession is signed for a period of 30 years, which is strategic for the group, since it allows it to secure the transportation of ore between the mine at Moanda and the port of Owendo, thus guaranteeing the ramp-up of manganese ore production to 3.5 million tonnes a year.
