About S11D

S11D Project

What is it?

Largest mining complex in Vale's history, the S11D Eliezer Batista Complex is an enterprise that integrates productivity with respect for people, and technology with environmental intelligence. In addition to increasing production in the state of Pará to 230 million metric tons per year, the project brings innovative solutions such as the truckless system, which replaces traditional off-highway trucks for conveyor belts and will reduce diesel consumption by about 70 percent. The dry processing (using iron ore's own natural moisture )will cut water consumption by 93% and it eliminates the need of tailings dams. Investments in innovation, combined with Vale's experience, enables a more efficient operation with less impact on the environment.

The project is located in the municipality of
Canaã dos Carajás, in southeast Pará.

For me, seeing the completed S11D Complex means much more than witnessing a new landmark in the mining industry. Besides featuring cutting-edge technology, low costs and high productivity, the Complex expresses Vale’s ability to make things happen.”

It goes without saying that our truckless in-pit crushing and conveying system is the big news in the iron ore industry. There is nothing else like it operating on this scale in the current market. It is a challenging and innovative way of operating, which requires changes to mine maintenance and planning routines. For this reason, the training and preparation of teams at all levels continue to be vital factors for the success of the new operation.”

Former Executive Director for Capital Projects, Vale

The name S11D Eliezer Batista Complex is a tribute to the notable Brazilian engineer Eliezer Batista, our company’s CEO during two different periods contributing to our growth.

244,000 m³ of concrete used. That equals 4 Maracanã stadiums.

190,000 native seedlings were planted. That equals 2,300 soccer fields.
