ArmInfo. The Zangezur Copper Molybdenum Combine is modifying its approach to dam reinforcement and raising at the Artsvanik tailing pond [zcmc.am]. The decision to change the methodology, which had been successfully applied and proven effective for nearly 50 years, follows a comprehensive stability monitoring program conducted by experts from a reputable international organization.
The new engineering solution will significantly enhance the overall stability and seismic resilience of the structure, effectively mitigating potential operational risks. Currently, the rock-soil fill material required for the embankment construction is being sourced directly from the tailing pond area. Future plans entail transporting waste rock from the administrative territory of the city of Kapan.
This initiative will help level the terrain and reclaim flat land parcels within Kapan's administrative boundaries, addressing a critical demand for urban and infrastructure development. Furthermore, the newly adopted method will ensure accelerated dewatering of the deposited tailings. The recovered water will be redirected to the existing process pumping station to be utilized for dust suppression systems and irrigation of green spaces.
Consequently, the transition to this advanced methodology guarantees higher reliability of the industrial infrastructure and promotes rational water resource management.
The Zangezur Copper Molybdenum Combine (ZCMC) and the Artsvanik tailing pond (often referred to as the Artsvanik dam) form an integrated technological and environmental chain of Armenia’s largest mining enterprise. ZCMC conducts ore extraction and processing at the Kajaran copper-molybdenum deposit, with an annual processing volume of approximately 22 million tons of ore. The waste from the ore-dressing plant (known as "tailings") is pumped to the Artsvanik tailing pond, located roughly 27–32 km away from the plant within the Kapan consolidated community. Transport is managed via a complex system of surface and underground pipelines. Operating since 1977, the Artsvanik facility is the largest tailing pond in Armenia, spanning a surface area of about 350–400 hectares.
