Serbia’s position in Europe’s critical minerals landscape will depend less on the size of its mineral reserves and more on its ability to convert geological resources into commercially viable industrial products. The country has significant mineral potential, including lithium and borates in the Jadar Valley, copper and gold resources around Bor and Majdanpek, lead-zinc deposits, historical antimony resources and metals contained in mining residues such as tailings and slags.

Mineral deposits alone do not create a critical minerals industry. Strategic value emerges only when resources can be extracted, processed, refined into marketable products and delivered consistently to industrial customers. Serbia already has several components of a potential value chain. The Bor copper complex, operated by Serbia Zijin Copper, includes mining operations, concentrators, a smelter and an electrolytic refinery. The nearby Čukaru Peki copper-gold mine, operated by Serbia Zijin Mining, has added a major source of high-grade copper concentrate to eastern Serbia’s mining sector.
The country also has downstream industrial assets, including the Stellantis vehicle manufacturing facility in Kragujevac, battery developer ElevenEs in Subotica and the proposed Jadar lithium-borates project, designed around production of battery-grade chemicals rather than raw ore exports.
Metallurgy Determines Strategic Mineral Value
Serbia’s existing industrial base provides a stronger starting point than countries relying primarily on exploration licences and geological estimates. However, mining, metallurgy, chemical conversion, battery materials production, cell manufacturing, electric-vehicle assembly and recycling are not yet connected into a single commercial ecosystem. The presence of lithium, copper, antimony or other strategic elements in geological formations does not automatically create an economic asset. A mineral resource cannot serve as industrial collateral without processing capacity, infrastructure, customers, environmental approvals and technical expertise capable of converting it into saleable products.
Many critical materials are not extracted from dedicated mines. Instead, they occur as secondary elements within larger mineral systems. Selenium and tellurium can follow copper through concentration and smelting, germanium and indium can occur in zinc-bearing minerals, while cobalt may be associated with copper or nickel operations. Gallium is typically recovered during alumina refining rather than through standalone mining operations. At the extraction stage, these elements often have no independent commercial value. Their economic importance appears only when processing facilities can identify, separate and purify them.
A Serbian copper concentrate may therefore contain additional strategic value beyond its copper content. If exported, foreign smelters and refineries may recover valuable by-products such as gold, silver, selenium and tellurium, depending on processing capability and contractual arrangements.
Bor Copper Complex Provides Domestic Processing Base
Serbia has partially avoided the limitations of concentrate exports through the integrated operations around Bor. Copper ore from eastern Serbia can move through concentration, smelting and electrolytic refining domestically. The modernisation of Serbia Zijin Copper’s TIR smelter significantly increased cathode production compared with the level inherited in 2018, when output was approximately 67,400 tonnes. By 2024, cathode production had increased to around 2.4 times that level, reaching approximately 160,000 tonnes.
During the same period, reported sulphur dioxide emissions per tonne of cathode declined from 8.93 kilograms to 0.27 kilograms. The domestic production of copper cathode gives Serbia a more advanced industrial position than a simple concentrate-export model. Refined copper can supply wire-rod producers, cable manufacturers, electrical equipment companies and other downstream industries.
The metallurgical system also creates opportunities to recover additional materials from intermediate streams. A further development of Serbia’s critical minerals strategy would require detailed accounting of economically important elements entering the Bor processing system. This would include tracking the grades, recovery rates and commercial outcomes of materials such as gold, silver, selenium, tellurium and platinum-group metals. Without such mass-balance information, the presence of strategic elements in ore does not necessarily mean Serbia produces those materials commercially.
Zijin Operations Expand Serbia’s Copper Position
Ownership structures also influence how mineral value is distributed. Serbia Zijin Copper is majority controlled by Zijin Mining, while the Serbian state retains a minority position. Serbia Zijin Mining, which operates the Čukaru Peki mine, is also part of Zijin’s Serbian operations.
Serbia benefits through employment, taxes, royalties, supplier activity, infrastructure investment and its ownership participation in former RTB Bor assets. At the same time, operational technology, capital decisions, concentrate management and international marketing remain linked to Zijin’s global network. The planned expansion of Bor and Čukaru Peki increases the importance of developing domestic processing capacity alongside mining output. Zijin has indicated that combined annual copper production from the two Serbian mining systems could eventually approach 450,000 tonnes.
Such growth would require additional capacity in concentration, smelting, power supply, water management, tailings handling, sulphur capture, transportation and export infrastructure. A mining expansion that grows faster than domestic metallurgy could increase reliance on concentrate exports. An integrated industrial strategy would therefore need to coordinate mining, refining, by-product recovery and residue processing.
Jadar Project Focuses on Chemical Conversion
The proposed Jadar lithium-borates project represents another stage of the same industrial challenge. The project concept developed by Rio Tinto was based on an underground mine combined with a chemical-processing facility producing battery-grade lithium carbonate rather than exporting untreated jadarite ore.
Based on production figures previously presented by Rio Tinto, the project could produce approximately 58,000 tonnes of battery-grade lithium carbonate, 160,000 tonnes of boric acid expressed in B₂O₃ units and 255,000 tonnes of sodium sulphate annually following ramp-up. The earlier investment estimate was US$2.4 billion, later associated with costs exceeding €2.55 billion, with figures subject to changes related to project design, environmental requirements and human-rights considerations.
Jadar would therefore represent a mining, processing and chemical-manufacturing project rather than a conventional extraction operation. Battery-grade lithium carbonate is a refined chemical product capable of entering cathode-material supply chains. Boric acid is used in sectors including glass, ceramics, insulation and agriculture, while sodium sulphate represents another potential commercial output. The project would retain more value in Serbia compared with a concentrate-export model by creating demand for engineering, laboratories, water treatment, maintenance, logistics and specialised industrial services.
Battery Manufacturing Requires Further Integration
Despite its potential, Jadar alone would not create a complete battery supply chain. Between lithium chemicals and electric vehicles are multiple industrial stages, including cathode active-material production, anode materials, electrolytes, separators, battery cells, modules, packs, battery management systems and recycling. Serbia has several elements of this chain but not yet a fully integrated commercial system.
ElevenEs has developed lithium-iron-phosphate battery technology in Subotica and opened a 10 MWh pilot manufacturing facility in 2023. The company’s planned next phase includes a 1 GWh annual-capacity megafactory, with an initial footprint of approximately 25,000 square metres and more than 350 planned employees. The challenge remains moving from pilot and early commercial production toward large-scale, financeable manufacturing.
The automotive sector provides a potential downstream anchor through Stellantis in Kragujevac. The facility underwent modernisation between 2022 and 2024 for the company’s Smart Car platform and electric vehicle production. Manufacturing of the new Citroën C3 began in 2025, complementing Stellantis operations in Trnava, Slovakia. These industrial assets are not automatically connected. Lithium chemicals produced in Serbia would still require commercial agreements, technical qualification, compatible battery chemistry, competitive pricing, traceability systems and long-term customer commitments before becoming part of a domestic mine-to-vehicle chain.
EU Partnership Depends on Value Chain Development
Serbia’s 2024 strategic partnership with the European Union on sustainable raw materials, battery value chains and electric vehicles was designed around five cooperation areas and included ambitions to develop an integrated electric-vehicle supply chain. The success of this partnership depends on investment reaching beyond extraction into processing and manufacturing.
The recognition of Jadar as an EU strategic project applies to the extraction segment, although the project concept includes domestic processing. Strategic status can support coordination and financing discussions, but it does not replace Serbian permits, environmental approvals, engineering completion or public acceptance. Jadar remained under care and maintenance in 2026, with no confirmed construction timetable. Previous production targets cannot be treated as current delivery schedules. The project continues to face opposition related to water resources, agricultural land, waste management, biodiversity, governance and institutional trust.
Secondary Resources Could Add Industrial Opportunities
Serbia’s historical mining activity has also created potential secondary resources. Mining and metallurgical operations have generated significant volumes of tailings, slags, flotation residues, smelter dust and other industrial materials. These materials represent environmental liabilities but may contain recoverable metals including copper, gold, silver, zinc, lead, selenium and tellurium. Their economic potential depends on factors including grade, mineral form, variability, processing costs, energy consumption, reagent requirements and waste-management obligations.
A residue containing valuable elements does not automatically represent a profitable secondary deposit.
A national inventory of mining and metallurgical residues could record volumes, chemistry, mineralogy, ownership, environmental status and possible treatment options. Where recovery is technically viable, projects could combine environmental remediation with secondary metal production. Such developments would require hydrometallurgical pilot plants, laboratories and cooperation between companies, the University of Belgrade Faculty of Mining and Geology, the Technical Faculty in Bor, the Institute for Mining and Metallurgy Bor and international technology providers.
Critical Minerals Policy Moves Toward Industrial Accounting
Serbia’s critical minerals strategy increasingly depends on project-level value-chain analysis rather than commodity lists. Future investments would need to define principal products, recoverable by-products, domestic processing stages, exported intermediates, power and water requirements, carbon intensity, waste streams, capital expenditure, ownership structures, fiscal contributions and final industrial customers.
Domestic processing requirements cannot be identical for every project. Some deposits may not justify standalone Serbian refineries, and forcing uneconomic facilities into investment agreements could undermine project viability. Investors should demonstrate why processing would take place abroad, what value leaves Serbia, how the country is compensated and whether regional or domestic processing options could become viable.
The strategic measure is not the quantity of extracted ore, but the amount of value retained through refining, chemical conversion, by-product recovery, industrial knowledge, skilled employment and supplier participation. Serbia already has a refined copper position because the Bor district includes metallurgy. It could establish a lithium and borates industry if Jadar or another project produces qualified chemicals under valid permits and verified environmental standards.
ElevenEs has created a foundation for battery manufacturing, while Stellantis provides an automotive production base, but the commercial links between these sectors remain to be developed. Serbia’s mineral potential becomes strategically valuable when resources leave the country as qualified industrial products supported by processing capacity, technical expertise, environmental controls and contracts with manufacturers.
