Using Murmansk Region, one of Russia's largest mining regions, as a case study, this paper examines the environmental safety challenges arising in the storage of mining and mineral processing waste (MMPW). It was found that MMPW causes environmental damage even after the deposit's exhaustion. While being stored, the MMPW composition experiences a major change in the process properties of
