The Arcos mining unit (MG) is integrated to the steelmaking process by providing essential flux agents to the UPV’s production. The rejects of the fluxing agent’s crushing process are then processed in a pulp thickening plant and decanted into bays. The fine dolomite is sold as an agricultural corrector and limestone powders used in cement production.

In 2011, CSN expanded and diversified its production line by inaugurating a clinker plant, which is a fundamental raw material for cement.
