We require several non-renewable inputs and supplies in the production processes, generating waste, such as:
Impurities in the mineral ore extracted from the earth
Tailings produced in the beneficiation of metallic minerals
Grease from furnaces, slag and jarosite from metallurgical processes
Dolomite powders, lime ash and plaster from chemical processes
Internal valuation alternatives.
External alternatives for recycling
Residues that are technically or economically unviable to process, confined to deposits.
To strengthen operational standards, our governance and alignment with best practices, in 2019 we implemented a new management process for tailing dams based on standards and guidelines issued by:
Water level monitoring
Hydraulic infrastructure studies
Slope stability analysis
