With a R$ 15 Billion Plan in Congonhas (MG), CSN Mineração Accelerates Production of Premium Iron Ore, Positioning Itself as a Strong Rival to Vale in the Global Market
With billion-dollar investments focused on its complex in Congonhas, Minas Gerais, the company seeks to establish itself as a rival to Vale, particularly in the growing segment of high value-added products.
CSN Mineração S.A. has embarked on an ambitious expansion plan aimed not only at increasing its production but also at redefining its position in the competitive global iron ore market.

The P15 Project, The R$ 15 Billion Plan to Expand Production in Congonhas
At the core of CSN Mineração’s expansion strategy is the Itabirito P15 Project. The company is investing R$ 15 billion in Minas Gerais between 2024 and 2027, with the majority, R$ 8 billion, allocated for a new beneficiation plant in Congonhas.
Expected to begin operations by the end of 2027, this plant will add 16.5 million tons per year (Mtpa) to the company’s capacity.
The goal is to leap from the current production of about 42 Mtpa to 68 Mtpa by 2028. The P15’s main differentiator is product quality: a pellet feed with iron content between 67.5% and 68%, intended for the production of “green steel” and with superior quality compared to Carajás, according to the company.
The Integrated System of Mine, Railway, and Port of CSN

CSN Mineração’s competitiveness is supported by an integrated logistics chain. The production from the Casa de Pedra mine in Congonhas is transported via the MRS Logística S.A. railway, in which CSN holds an 18.63% stake.
The final destination is the Coal and Minerals Terminal (TECAR) at the Port of Itaguaí (RJ), managed by CSN Mineração itself. This terminal has an export capacity of over 42 Mtpa.
This integrated structure gives the company essential control over the costs and efficiency of transporting its production to the international market.
The Dispute with the Rival to Vale, Competition in the Premium Iron Ore Market
The expansion of CSN Mineração is often seen as a move to intensify competition with Vale, the giant of the industry. Although the scale of operations is very different, CSN aims to position itself as a strong rival to Vale in the strategically lucrative niche of high-quality iron ore.
Production and Quality: while Vale produces hundreds of millions of tons, CSN’s target of 68 Mtpa is significant. CSN’s focus with the P15 Project is to compete on quality, producing a pellet feed with superior iron content that commands premium prices in the market.
Costs and Strategy: Vale has a lower overall production (breakeven) cost. However, CSN’s strategy is to focus on value-added products and customer diversification, with long-term contracts already established with Japanese and Middle Eastern steelmakers for the production of P15, reducing dependence on the Chinese market.
ESG as a Differentiator: CSN highlights its independence from upstream tailings dams since 2020, an important ESG (Environmental, Social, and Governance) differentiator in an industry marked by disasters.
The Challenges in Congonhas, The Socio-Environmental Impacts of Expansion
CSN’s expansion in Congonhas occurs in a region of high socio-environmental sensitivity. The city, a historical heritage site, has been dealing with the impacts of mining for decades. The main concerns of the local community and the city hall include:
Air Pollution due to ore dust.
Impacts on Water Resources, as the expansion takes place in the Serra do Esmeril, crucial for aquifer recharge.
The Safety of Large Piles of Waste and Tailings, such as the PDER from Fraile, located less than 400 meters from the urban area.
The lack of dialogue and transparency from the company with the community has been criticized. Overcoming this distrust and securing a Social License to Operate (SLO) is one of the greatest challenges for the project’s success.
Is CSN Mineração Ready to Be the Major Rival to Vale?
CSN Mineração is at a transformative moment. The billion-dollar bet in Congonhas, focusing on high-quality products, has the potential to generate significant value and strengthen its position in the global market.
The company does not seek to compete in total volume with its main rival to Vale, but rather to become a leader in the growing and profitable niche of premium iron ore.
The success of this endeavor will depend on the timely and budget-compliant execution of the P15 Project, the ability to capture market premiums for its high-quality product, and, fundamentally, on the ability to build a relationship of trust and sustainability with the Congonhas community.
If it can overcome these challenges, CSN Mineração will consolidate its place as a globally relevant player and a force to be recognized in the mining industry.
