Choapa which will serve as support for Minera Los Pelambres in periods of water
scarcity.
Another of its projects is the Suppression of dust with electromagnetism,
this proposal came from Innovaminerals, the innovation program of Antofagasta
Minerals, to reduce the emission of dust through electromagnetic technologies; The
pilot will be implemented in 2019.
Intending to mitigate accelerated melts as a result of climate change in snowy
mantles and glaciers, the Innovation Board approved in 2018 a project consisting
of the installation of removable covers of systems that include special textiles that
delay melting. The Project is called “Glacier Coolers” the pilot will be implemented
in 2019.
Vale, considering the facts that occurred in Córrego de Feijão, the company’s
leaders and technicians were mobilized to rethink, discuss and propose solutions
for the future of the business. Among the immediate actions evaluated, is the tailings filtering and stacking project, as an alternative solution to the need to build
new dams. In addition to reducing the use of dams, Vale is considering investing,
between 2020 and 2023, approximately US $ 390 million in the implementation of
dry stacking technology in Minas Gerais. The technique allows filtering and reusing
the tailings water and enables the tailings to be piled, thus reducing the use of dams.
Vale is also developing projects to reduce diffuse emissions (particulate matter) in its
operating units by adopting measures such as the improvement of sprinkler systems
and the use of dust suppressing products. In 2018, Vale, in partnership with the
Federal University of Espirito Santo—UFES, developed and has already patented a
