Drained Stacking Technology as a Water Management Strategy and Elimination of Dams
ABOUT IT
The project consists of the implementation of Drained Stacking Technology in the mineral beneficiation process, with the objective of eliminate conventional dams and optimize the water use in the production process.
The initiative involved:
Installation of two hydrocyclone batteries, with 14 units each, in the old Dam 2;
Operational transformation of the structure, requiring technical resilience e process adaptation;
Efficient separation between solids and liquids., allowing drained stacking of the tailings and return of clarified water to the industrial process.
Results and Objectives
Objectives
Reduce the intake of new water., promoting water conservation;
Decharacterizing old dams, eliminating geotechnical risks;
To promote safer and more environmentally responsible mining.;
Align operations with the principles of a circular economy..
Results (to date / achieved)
Reduction in new water intake by approximately 3.5 million m³;
Decharacterization of the old dam, eliminating associated risks;
Improved operational efficiency and process safety.;
Strengthening the commitment to sustainability and the circular economy..
