A person no longer needs to climb into a cab to run it.
Em junho de 2026, a Vale inaugurou em Itabira aquilo que pode ser o primeiro capítulo de uma nova era na mineração brasileira: uma usina inteiramente governada por inteligência artificial, onde máquinas ajustam variáveis em tempo real e trabalhadores operam à distância, longe dos riscos que por gerações definiram a profissão. Com investimento de R$200 milhões e ganhos de produtividade de 25%, a Conceição 2 não é apenas uma modernização tecnológica — é uma reconfiguração do que significa extrair riqueza da terra. A pergunta que o projeto deixa no ar não é se a mineração mudará, mas com que velocidade essa transformação se espalhará.
- A Vale apostou R$200 milhões numa instalação onde a inteligência artificial não auxilia o trabalho humano — ela o conduz, monitorando mais de 400 variáveis simultaneamente e ajustando operações sem intervenção manual.
- O salto de 9 para 11,2 milhões de toneladas anuais e o aumento de 40% na produção de pellet feed de alto valor mostram que a automação não é apenas mais segura — é economicamente decisiva.
- 122 trabalhadores foram treinados em realidade virtual para operar um ambiente que já não exige presença física nos pontos mais perigosos, redesenhando o contrato entre mineradora e mão de obra.
- A redução de 26% no teor de ferro nos rejeitos e a reciclagem de 92% da água usada no processo posicionam a eficiência tecnológica como resposta concreta às pressões ambientais sobre o setor.
- Com expansão prevista para Brucutu até o fim de 2026 e para Vargem Grande na sequência, a Vale trata a Conceição 2 não como experimento, mas como modelo a ser replicado em escala.
Na última quarta-feira de uma manhã de junho, a Vale ligou em Itabira uma usina que a empresa passou dezoito meses e 200 milhões de reais reconstruindo do zero. A Conceição 2, no coração de Minas Gerais, não foi apenas modernizada — foi reimaginada. Cinquenta e uma soluções tecnológicas desenvolvidas com a ABB foram embutidas em cada etapa do processamento de minério. Mais de cem câmeras com sensores de IA vigiam o complexo. Quase 7.300 instrumentos alimentam o sistema com dados contínuos. Operadores sentados em uma sala de controle distante da maquinaria real supervisionam tudo — e, em grande parte, as próprias máquinas se ajustam sozinhas.
Os resultados do período piloto são concretos. A produtividade subiu 25%. A produção de pellet feed, produto de alto valor, cresceu 40%. O teor de ferro nos rejeitos caiu 26%, porque o sistema analisa a qualidade do minério em tempo real e faz ajustes imediatos que extraem mais valor de cada tonelada processada. A capacidade anual saltou de 9 para 11,2 milhões de toneladas. E 92% da água utilizada na filtragem é reciclada de volta ao processo — uma eficiência que só se torna possível quando um sistema enxerga e otimiza centenas de variáveis ao mesmo tempo.
Para os 122 trabalhadores treinados nesse novo ambiente — muitos deles por meio de simulações em realidade virtual —, a mudança é também uma promessa: menos exposição a espaços confinados, maquinário pesado, poeira e calor. O trabalho perigoso não desapareceu, mas foi empurrado para longe do corpo humano.
A Vale deixou claro que a Conceição 2 é um template, não uma exceção. A mina de Brucutu deve operar sob o mesmo modelo até o fim de 2026, seguida por Vargem Grande. Para o vice-presidente técnico Rafael Bittar e o CEO Gustavo Pimenta, liderar o setor hoje significa ser mais tecnológico, mais responsável e mais atento ao que o mundo exige de uma grande mineradora. A inauguração em Itabira marca menos um fim do que um ponto de partida.
On a Wednesday in June, Vale switched on a mining operation unlike any the company had run before. The Conceição 2 plant in Itabira, in central Minas Gerais, had been rebuilt from the ground up to run on artificial intelligence—not as a supplement to human work, but as the operating system itself. The company had poured 200 million reais into the transformation, and the numbers coming back suggested the bet had paid off. Since the pilot phase ended, productivity at the facility had climbed 25 percent.
The plant processes 11.2 million tons of ore annually, but the real innovation lies not in volume but in how the work gets done. Over eighteen months, Vale's engineers and their partners at ABB, the automation giant, embedded 51 distinct technological solutions throughout the facility. More than a hundred cameras equipped with AI sensors watch the complex. Nearly 7,300 instruments—sensors, gauges, advanced measurement devices—feed data continuously into the system. The plant monitors and adjusts more than 400 variables across every stage of ore treatment, all of it visible to operators sitting in a control room miles away from the actual machinery. A person no longer needs to climb into a cab or stand beside a piece of equipment to run it. The machines make decisions on their own, adjusting themselves in real time as conditions shift.
Vale trained 122 workers for this new world of work. The company used virtual reality to let them practice operations and walk through dangerous scenarios without physical risk. The connectivity infrastructure had to be rebuilt too, hardened to handle the constant stream of data flowing between sensors and control systems. What emerged is a facility where human beings are no longer exposed to the most hazardous parts of mining—the confined spaces, the moving machinery, the dust and heat. The work happens remotely, or it happens autonomously, or it doesn't happen at all because the system has optimized it away.
The productivity gains are real and measurable. The plant produces a premium product called pellet feed, and since the AI system came online, the share of that high-value output has jumped 40 percent. On the other end of the process, the company is throwing away less. Iron content in the tailings—the waste left after ore processing—has dropped 26 percent. This happens because the system analyzes ore quality in real time as it moves through the plant, allowing immediate adjustments that squeeze more value from each ton of rock. In 2024, before full automation, Conceição 2 produced 9 million tons. This year, it is capable of 11.2 million.
Vale is treating this plant as a template. The company expects the Brucutu mine, also in central Minas, to be operating under the same model by the end of 2026. Vargem Grande, near Belo Horizonte, will follow. Rafael Bittar, Vale's technical vice president, framed the project as essential to the company's future. Mining, he said, needs to become safer, more sustainable, and more competitive. The CEO, Gustavo Pimenta, has been talking about Vale reclaiming its place as a leader in the industry—and Bittar suggested that leadership now means being more technological, more responsible, more attuned to what the world expects from a major mining company.
There is also a sustainability angle worth noting. The plant recycles 92 percent of the water used in ore filtering. After the mineral and tailings have been separated in the final processing stages, the water cycles back into operation rather than being discharged. It is the kind of efficiency that only becomes possible when a system can track and optimize hundreds of variables simultaneously—when a machine can see the whole process and adjust every part of it in concert.
The inauguration of Conceição 2 marks a threshold. Vale has moved beyond testing whether AI can improve mining operations. The question now is how quickly the company can replicate the model across its portfolio, and whether other miners will follow. The plant stands as proof that the future of mining does not require more people in more dangerous places. It requires fewer people in safer ones, working alongside systems that never sleep and never make mistakes born of fatigue.

La Conversación del Hearth Otra perspectiva de la historia
Why does a mining company need to automate this aggressively? Isn't Vale already profitable?
Profitability is one thing. Staying competitive when the world is watching your environmental and safety record is another. Every worker you remove from a hazardous task is a worker who goes home. Every ton of waste you eliminate is a ton you don't have to manage or remediate.
But 122 workers trained for new jobs—what happens to the people who used to do the work the machines now do?
That's the question Vale isn't fully answering in this announcement. The company trained 122 people for the new operation, but we don't know how many people the old Conceição 2 employed, or whether those workers were retrained or displaced.
The 25 percent productivity jump—is that because the machines work faster, or because they work smarter?
Both, but mostly smarter. The system analyzes ore quality in real time and adjusts the process on the fly. It's not just running the same steps faster. It's eliminating waste, optimizing for premium products, reducing what gets thrown away. That's a different kind of efficiency.
And the water recycling—92 percent seems high. How does that change the company's footprint?
It's significant. Mining is thirsty work, and water is increasingly scarce in Brazil. If Vale can prove it can run a major facility on recycled water, that becomes a selling point to regulators and communities. It also reduces the company's vulnerability to drought.
So this is really about Vale positioning itself for the next decade?
Exactly. The CEO is talking about reclaiming leadership. That means being the company that figured out how to mine safely, sustainably, and profitably all at once. Conceição 2 is the proof of concept.
