Vale opens AI-powered plant in Minas Gerais state, boosts productivity by 25%
Brazilian miner Vale inaugurated its first high-tech processing plant using artificial intelligence after modernizing a facility in Minas Gerais state, the company said on Wednesday, achieving a 25% productivity gain in less than two years.
The Conceicao 2 unit is now capable of producing up to 11.2 million metric tons of iron ore per year, compared to 9 million tons in 2024, Vale said in a statement.
The modernization integrated advanced automation, monitoring, and data intelligence to optimize more than 400 variables in the iron ore beneficiation process.
The pilot project also increased by 40% the share of direct reduction pellet feed — a product considered strategic for steel decarbonization — and improved mineral recovery.
“The model plant is more than a project: it represents a new way of operating,” said Carlos Medeiros, Vale vice president of operations.
Digitalization has also reduced manual interventions and improved safety, with remote equipment operation and centralized monitoring, Vale said.
The firm intends to use the model as a reference for other units.

Vale’s top shareholder pushes for meeting on chairman’s removal

Brazil’s Vale, one of the world’s largest iron ore producers, said on Thursday it received a request from its top shareholder, pension fund Previ, for a shareholders’ meeting to vote on the removal of chairman Daniel Andre Stieler.
Previ, which manages pensions for employees of state-run lender Banco do Brasil, proposed appointing Jose Mauricio Coelho to Vale’s board and backing current board member Manuel Oliveira as chairman, the miner said in a filing.
According to Vale, Previ has argued that Oliveira will contribute to “the strengthening of governance practices, the improvement of strategic management and the alignment with the interests of shareholders and stakeholders.”
The mining company did not release the document it received from Previ. The pension fund did not immediately respond to a request for comment, sent outside business hours.
Vale said its board is assessing the steps required to convene the shareholders meeting.
Previ holds about a 7% stake in Vale, according to regulatory documents. The fund swapped its own head last month, naming Marcio Antonio Chiumento as CEO after Joao Luiz Fukunaga resigned.
Chiumento joined Vale’s board earlier this year.
