A new horizon
Recovering copper and other critical minerals from mining waste in Europe
The Medet Tailings project is an innovative clean technology project focused on developing a sustainable European supply chain for copper and other critical raw materials from the recycling of historic mine tailings, transforming what was once considered waste into a critical resource for the energy transition.
By recovering copper from the recycling of mine tailings at the Medet site, the project aims to contribute to the EU’s goals of strengthening the European supply chain for critical raw materials and improving circularity and sustainability.
In addition, the Project will have positive environmental benefits for the site and surrounding areas, through the remediation of environmental damage caused from historical mining at the location and reinstatement of the original valley.
About the Project
Located in central Bulgaria, the Medet tailings deposit is the largest resource of copper (Cu) tailings in Eastern Europe.
The 2,200-hectare site contains approximately 110 million metric tonnes (Mt) of waste (tailings) material, from the mining of copper-molybdenum porphyry deposits.
In addition to the tailings deposit, the site also includes existing infrastructure for the purpose of reprocessing the waste material.
The site is owned and operated by MBS EAD, a subsidiary of Altilium Metals Ltd, a UK-based clean technology group supporting the transformation of the global energy sector from fossil-based to zero-carbon
