Dams

Our priority is safety, always

To ensure the stability of our geotechnical structures, we have a management system that evaluates different aspects of the structures’ safety, being continuous evaluated by renowned external professionals, following best international practices.

We comply with current legislation, and all dams and piles are stability certified, ensuring full compliance with legal and sector standards to provide safety to the community.

Do you know how we dispose our tailings and waste?

Backfill
Dry Stacking
Dams

It is the in-pit tailings storage by backfilling tailings into the voids of underground pits with the purpose of increasing the structural mine stability, providing platforms and improving ore recovery.

Underground tailings disposal in mining pits can occur when the waste is considered inert, excluding the possibility of water or soil contamination.

Also called as pile, filtered tailings deposit or dewatered tailings, the tailings pulp that outcomes from the mineral processing undergo to filtering, drying, handling process (combined or single), until it contains moisture levels under 20%.

By pulp water extraction (mixture of liquid fluid with ore or tailings), the solid part is stored or formed into piles, ensuring environmental impacts reduction.

A dam is a structure built for the purpose of permanent or temporary water, liquid substances or liquids and solids mixtures containment, accumulation or storage.

The term “dam” includes not only the dam itself, but also all associated facilities, such as: overflows and spillways, reservoir, approach channel, diversion structures, return channel, water intakes, water catchment, saddle dike, among others.
