Expected impacts

• Mitigate climate change by reducing the use of inland water to process ore (inland waters are permanent freshwater bodies that lie above or below the surface and removed from coastal areas - except for rivermouths and other waterways).
• Apply greater water efficiency by taking advantage of the tailings deposit water resources that do not currently recirculate.

• Improve the physical stability of tailings. 

• Decrease water stress (this occurs when the demand for water is higher than the amount available during a given period or when its use is restricted due to inferior quality).

Proposed solutions

• Develop engineering projects for the recirculation of the tailings deposits Ovejería (in Andina); Carén (in El Teniente) and Pampa Austral (in Salvador) optimizing costs and deadlines.
• Integrate the water efficiency processes of all divisions.

• Optimize the percentage of water recovery from tailings storage facilities.

• Create alliances to identify and incorporate best practices on the job site.
• Take advantage of the clear waters that are recovered from clear water tailings lagoons to be used in our productive processes.
• Incorporate new technologies and alternative solutions to traditional recirculation.

• Improve and make the technical limits flexible with the intention that maximum flow can be recirculated for each tailings storage facility. 

Progress

RECIRCULATION PROJECTS

Works have already been designed to recirculate the waters contained in the clear water lagoons of the Pampa Austral, Ovejería and Carén tailings storage facilities.
