Mineral raw materials of Serbia on the list of critical minerals of the European Commission (CRM EU-2020) during the Covid-19 pandemic and harmonized in the UNFC-2009 system and the PERC standard

The existence of mineralization, mining and deposits non-ferrous precious other metals (Pb-Zn, Ag; Cu, Au, as well B-Li, Mg, Sb, etc.) in the territory Serbia is conditioned by structural-geological-metallogenetic structure processes formation mineral raw materials a certain period geohistorical development. Mining activity Serbia, i.e. extraction metal ores, goes back thousands years, which resulted "production" significant accumulations industrial waste. These facts indicate potential possibility recovering through technological waste material recycling. Mineral are primary sources, accumulated secondary sources providing resources such Pb-Zn, Co, Ni, Al, Li, W, Bi, In, Te, Ga, Ge, REE others, many on list CRM EU-2020 or 2023. Critical minerals professional-formal term not defined due to specific way extent occurrence nature, exhaustibility non-renewable reserves, provision countries regions with solid socio-economic conditions (world crises, wars, embargoes, pandemics, become deficient, missing (on market), terms supply chain. During Covid 19 pandemic, publicly available data critical were analyzed, when it was assessed that e.g. for chain health sector, only ten them (Sb, Ba, B, F, ...). classified into categories classes geological reserves (classes reserves) can, reporting purposes, be harmonized Resources/Reserves from international standards (PERC, JORC, Ni-43 101 codes UNFC).
