Tailings case studies
Gelado Project
Brick factory
In November 2020 we started operation of our Pico concrete block manufacturing facility, our first pilot plant producing building and construction products from mine tailings. Located at our Pico mine in Itabirito (MG), the facility will incorporate circular economy practices in our iron ore processing operations at this site.
Following initial testing, the plant is expected to repurpose annually 30,000 metric tons of tailings that would otherwise be stored in piles and dams to produce 3.8 million pre-molded concrete products for the building and construction industry, including interlocking pavers and structural and architectural concrete blocks.

Arquivo Vale
Vale has conducted research on potential applications for mine tailings since 2014. Over the two first years of operation, Vale will invest approximately R$ 25 million in research and development (R&D) in collaboration with the Minas Gerais Federal Center for Technological Education (CEFET-MG). Ten researchers from the center are involved in the research program, including professors, lab technicians and graduate, undergraduate and associate degree students.
Following the initial R&D stage at the Pico mine, Vale plans build similar concrete block facilities at other operations in Minas Gerais. We have also partnered with more than 30 organizations—including universities, research centers and local and overseas companies—to develop solutions for repurposing mine waste in a wide range of industries.
