Vale will eliminate the use of water in Carajas iron-ore processing by 2027

Vale executives announced on Tuesday that the mining giant aims to end the use of water in the processing of iron ore by its Carajas Mines by 2027. The company also plans to expand pellet feed production at the complex located in northern Brazil through the reuse and recycling mine waste. Vale stated that by eliminating the use of water for iron ore beneficiation, it would reduce the amount of waste, known as tailings, in the production process. This would also eliminate the need to build new dams and save money.

Carajas in Brazil's Para State is the largest open-pit iron ore mining complex in the world. A part of its operations has already adopted dry processing. Vale's Northern System, which comprises 90% of its operations, no longer uses water for beneficiation.

By the end of 2027, they will be completely dry. "The Northern System will run 100% on natural moisture," Vale Director Gildiney Sales stated. Gildiney Sales was referring to a region that produced 177.5 millions metric tons iron ore in the year 2024. This is more than half Vale's overall output.

The company said it also expects to double its production by 2026 compared to the current year for its Gelado project, which produces high-quality feed pellets using tailings that have been stored at the Gelado Dam since 1985.

According to the company, its production is expected to reach 5 million tonnes next year, and 6 millions tons by 2027.
