Minewater neutralization

As a result of the intense mining activity that has taken place in Peru during all these years, there have been huge pollution environmental problems.

One of the most important problems caused is the water acidification, which constitutes the so-called acid mine drainage (AMD), with the consequent dissolution of heavy metals.

Acid drains can have a varied origin. Acidity originates by contacting sulfides, of mineral origin, in fitting rocks or large mineralization, which oxidize in the presence of oxygen and water. The main sulfurous mineral that causes acidity is pyrite.

AMDs require treatment and control prior to discharge in the receiving body to reduce environmental contamination and comply with current legal regulations.

DYNAFLUX, as part of its integral solutions, offers a physicochemical treatment design, from the conceptualization solution to the start-up of the treatment plant to obtain treated water in accordance with the country’s legal regulations.
