Six sedimentation ponds were built to treat water from the processes of "La Y" mine. GelocBulk coagulant is applied to the treatment process. A pumping system to use mine water in gold processing is also needed. This allows recirculation of this water in its entirety and contributes to a reduction in the surface water used during the processing stage that was previously obtained from the concession in the Tigüí River. The project also implies a reduction in dumping volumes. The Tigüí River (Municipality of Zaragoza) is an area of low-pressure levels on water resources; however, it has a high impact due to pollution caused by deforestation and the execution of unregulated mining activities.

Project Results

Reduction in surface water use of 253,497 m3/year corresponding to 50%.
