Kobaloni Energy Zambia is developing a major battery-grade cobalt sulphate refinery in Zambia, aiming to transform cobalt hydroxide into a higher-value chemical product for use in the production of battery cathodes. The project is being positioned as a potential new link between African cobalt resources and European battery manufacturing, with Kobaloni targeting customers that require traceable critical minerals outside the traditional Asian processing chain.
6,000 Tonnes of Cobalt Sulphate Capacity Planned
Kobaloni’s initial development plan calls for production equivalent to approximately 6,000 tonnes of contained cobalt per year in the form of cobalt sulphate. The company has also identified the potential to double production capacity as the operation develops. At the initial output level, Kobaloni estimates that its production could provide enough cobalt to support batteries for approximately one million electric vehicles each year.
The proposed refinery is therefore intended to operate at a scale capable of supplying a meaningful volume of material to the rapidly expanding battery and electric-vehicle supply chain. Rather than exporting cobalt hydroxide as an intermediate product for further processing overseas, Kobaloni aims to carry out the chemical refining and value addition in Zambia.
Strategic Project Under EU Critical Raw Materials Framework
The project has gained strategic significance through its recognition as a strategic non-EU project under the European Union’s Critical Raw Materials Act. Kobaloni has designed the refinery around the needs of European battery manufacturers, with an emphasis on producing traceable cobalt sulphate that can enter the European battery supply chain.
This approach differs from the traditional model in which African cobalt intermediates are shipped to major Asian processing centres for refining and conversion into battery chemicals. By producing battery-grade cobalt sulphate in Africa, Kobaloni is seeking to capture more value closer to the source of the raw material while establishing a direct supply route to European industrial customers.
Project Cost Estimated at €75 Million
Published project information has placed the estimated development cost at approximately €75 million, with a projected debt requirement of about €55 million. Africa Finance Corporation (AFC) has previously indicated interest in providing as much as US$100 million in potential financing support.
An expression of interest should not be interpreted as committed project finance. Any eventual funding would depend on due diligence, definitive financing documentation and the fulfilment of conditions precedent. The relatively modest capital requirement compared with a conventional mining development is partly a consequence of Kobaloni’s focus on refining rather than developing a new cobalt mine.
Refinery Model Reduces Dependence on One Mine
One of the project’s key strategic features is that Kobaloni is developing a refinery rather than a standalone cobalt mining operation. The facility could potentially process cobalt hydroxide sourced from Zambia and the neighbouring Democratic Republic of Congo, giving the company access to a broader regional feedstock base.
That model could provide greater flexibility than a refinery tied exclusively to a single mining operation. Instead of depending entirely on the production profile of one mine, Kobaloni could potentially source suitable cobalt hydroxide from multiple suppliers. The approach also reflects the structure of the Central African copper-cobalt region, where significant quantities of cobalt are produced as a by-product or co-product of mining operations.
Feedstock Security Is Central to Project Bankability
For Kobaloni, however, the ability to secure adequate feedstock will be one of the most important factors determining whether the refinery can achieve its planned production levels. A refinery can only operate efficiently if it has access to reliable volumes of suitable cobalt hydroxide. Long-term supply agreements, consistent quality and predictable logistics will therefore be critical to the project’s financing and operating model.
The chemical composition of the feedstock is equally important. Impurity levels can affect recovery rates, reagent consumption, processing costs and the quality of the final cobalt sulphate product. Kobaloni will consequently need to demonstrate that its proposed processing technology can deliver reliable recoveries across the range of feedstocks it intends to accept.
European Offtake Could Determine Commercial Success
Securing long-term offtake agreements with financially strong European customers is another major consideration. Producing battery-grade cobalt sulphate is only one part of the value chain. The refinery also needs qualified customers capable of purchasing the material under commercially viable terms.
Strong offtake commitments could improve the project’s financing prospects by providing greater visibility over future revenues. They could also help demonstrate that the refinery’s product meets the technical, quality and traceability requirements of European battery and cathode manufacturers. Without firm customer commitments, Kobaloni could remain exposed to cobalt price volatility and working-capital requirements, even if the refinery successfully reaches production.
Traceability Adds Strategic Value
The project’s focus on traceable cobalt could become increasingly important as battery manufacturers and European policymakers place greater emphasis on supply-chain transparency. European manufacturers are seeking to diversify sources of critical raw materials while gaining greater visibility into where minerals originate and how they are processed.
Kobaloni’s proposed model could therefore offer more than simple geographic diversification. Processing cobalt hydroxide into battery-grade cobalt sulphate within Zambia could create a more clearly defined supply chain between African feedstock producers and European battery customers. The commercial value of that proposition, however, will depend on the refinery’s ability to maintain robust traceability systems and meet the technical and sustainability requirements imposed by prospective customers.
Energy, Reagents and Recovery Rates Remain Key Risks
Beyond feedstock and offtake, the project’s economics will depend on several operating variables, including energy prices, reagent consumption, metallurgical recovery and plant availability. Chemical refining can be sensitive to changes in input costs. Higher electricity or reagent prices could put pressure on operating margins, while lower-than-expected recovery rates could reduce the volume of saleable cobalt sulphate produced from each tonne of feedstock. These factors will therefore be closely examined by lenders and potential investors before the project reaches financial close.
Kobaloni Could Strengthen Africa-Europe Cobalt Trade
If successfully developed, Kobaloni could become an important new link in the Africa-Europe critical minerals supply chain. The project would seek to move cobalt processing beyond the export of intermediate material and into the production of a higher-value battery chemical in Zambia. At the same time, its European market focus could help establish an alternative supply route for manufacturers seeking to reduce dependence on concentrated global processing networks.
The project’s strategic appeal therefore rests on the combination of regional cobalt feedstock, African value addition, traceable production and access to European battery markets. The next major test will be commercial and financial rather than simply geological. Kobaloni will need to secure dependable feedstock, demonstrate processing performance, control energy and reagent costs and secure credible European offtake.
Ultimately, the project’s bankability will depend on whether those elements can be brought together into a financing structure capable of supporting construction and long-term operations. A refinery without secure feedstock risks becoming an underutilised chemical facility, while a refinery with adequate feed but no reliable customers remains vulnerable to cobalt price cycles and working-capital pressure. For Kobaloni, the opportunity is therefore substantial, but the route from a strategically important project to a fully financed and operating European-facing cobalt sulphate refinery will depend on converting its supply-chain proposition into firm commercial contracts and bankable project commitments.
