Our dam management approach
Our industrial complex consists of six dams monitored 24 hours a day, seven days a week.*Decommissioning is the process where the structure loses its dam
characteristics and its area is reintegrated into the environment.
The dams in operation are built using the downstream raising method, in other words, the embankment is built 20 centimeters at a time on a sturdy foundation. The works are monitored by specialized technicians who perform technological control activities, which aim to ensure that the technical design premises are being met.
The waste from the beneficiation process is deposited in dams according to the strategic disposal plan, prepared by CBMM in partnership with specialized companies. In addition to ensuring the best waste disposal, it also allows for the recirculation of approximately 96% of the water used in the entire industrial process.
Sediment Containment
Rainwater that carries sediments is contained by dams, with the aim of promoting their clarification. During dry periods, the stored sediments are removed from the containment dam and deposited in appropriate locations, in order to maintain the accumulation capacity.
Water Storage
The water dam is operated through collection in a pumping system to meet industrial demands that are not met by the recirculation of water in the waste dams.
Monitoring
The structures are monitored full-time, using automated instrumentation and high-resolution cameras connected to the integrated monitoring center – CMI. In addition, field teams periodically inspect the dams, monitor the instruments and identify the state of conservation of the structure.
Maintenance
Maintenance of the dams is carried out by an in-house team with the support of specialized companies. Any and all necessary maintenance is carried out within engineering criteria and with full monitoring of the activities.
