Kokkinolakkas Tailings Management Facility


KOKKINOLAKKAS DRY-STACK TAILINGS MANAGEMENT FACILITY

Innovative and safe tailings management

The Kokkinolakkas Tailings Management Facility is an integrated, state-of-the-art and properly protected dry-stack area.

The development and operation of the site is a project that supports both active operations and rehabilitating the area, as it is used to safely stack not only tailings generated during contemporary production at the Olympias mine, after excess water is removed, but also historical deposits from previous mining activities (1969-1995), which have existed in the area for decades.

Dewatering of tailings: internationally recognized best practice

The advanced technology of dewatering tailings is the safest tailings management method in our industry with the smallest ecological footprint. It is internationally recognized as the best practice.

Based on this practice, tailings from the facilities at Olympias and materials cleared off from historic, inactive stack areas, are converted into solids with the dewatering method. Removing excess water from the tailings, leaves over a sandy material which is then safely stacked and compressed, reducing potential risks from storage as a liquid.

Advanced design

The Kokkinolakkas Tailings Management Facility has been constructed with the latest technology and the highest standards. It is a state-of-the-art structure, valuable to the area’s safety and environmental balance.

The dry-stacking site has been designed to stay safe, secure and protected. It incorporates a waterproofing system exceeding the project's licensing requirements. Moreover, it has been built in accordance with sanitary landfill specifications, surpassing the standards for safe waste storage and management.

Another advantage is that the dry-stack tailings occupy much less space and increase geotechnical safety in the site by mitigating issues of water seepage. Dry stack technology enables the maximum amount of water to be recycled and reused in the production cycle, which in turn minimizes the consumption of fresh water.
