Update: Lithium from Europe: hurdles and successes
A lot has happened in lithium extraction in the past year, and fortunately mainly in Europe. This is also urgently needed if we want to become less dependent on South America, Australia and China when it comes to battery production. Especially as extraction from the largest European deposits is very uncertain. An update to the article from May 2024, which you can read below.
The mine in Beauvoir is just one part of the Emili project in France. Facilities for processing the lithium-bearing rock are now also being built.Shortly after the publication of our first article ‘Lithium from Europe’ (see at the end of this article, May 2024), the media reported that lithium mining in Serbia's Jadar Valley could soon become a reality. The EU and Serbia had signed an agreement to this effect. That was a bombshell. It has long been known that there is an extremely large lithium deposit in western Serbia. However, following mass protests, the Serbian government revoked the mining licence it had granted in 2022. The fears of the people were - and still are in parts of the population - that the groundwater could be damaged by the mining and there could be disadvantages for the water supply. Under the new agreement, Germany is to play a key role in securing access to lithium for Europe. New environmental impact studies by the British-Australian mining investor and the reference to the now higher environmental and sustainability standards have so far failed to dispel the Serbian company's concerns.
The deposit contains the mineral jadarite, a sodium-lithium-boron-silicate-hydroxide, which was first discovered there in 2004. It is estimated to contain 136 million tonnes of ore with a high lithium and boron content. This would make it possible to produce around 58,000 tonnes of lithium carbonate per year - enough for one million electric vehicles. In addition to lithium, boron is also to be extracted there. Rio Tinto continues to endeavour to convince the public of the benefits of the project. The company is also investing in battery manufacturer InoBat, which is building a development facility and a pilot plant in Slovakia and has plans to build several gigafactories, including one in Serbia. Nevertheless, the future of the project, which could make Serbia one of the largest lithium producers in the world, remains uncertain.
Headwinds for Zinnwald lithium extraction too
Other lithium extraction projects are also facing increasing headwinds from the public: Zinnwald Lithium GmbH, for example, which announced in June 2024 that the deposit was larger than expected due to new drilling. Annual production of up to 18,000 tonnes of lithium is possible. Zinnwald Lithium has applied to the EU Commission to be categorised as a strategic project in accordance with the new Critical Raw Materials Act (CRMA). This would put it in the fast lane - the authorisation procedure would have to be completed within 27 months. Citizens are taking to the barricades against this. They doubt that the low lithium content of the ore makes the operation economically viable and are calling for a feasibility study. However, the company wants to start the authorisation process in 2025. However, the financing has not yet been finalised.
A production plant for lithium hydroxide is also being planned at a second site in Saxony - Altenberg and Falkenhain. Driven by Deutsche Lithium, an AMG subsidiary.
First quantities of lithium hydroxide already coming from Industriepark Höchst
The extraction of lithium using the geothermal process, as used by Vulcan, is looking much better. Things are progressing almost as planned. In August 2024, the company began commissioning its Central Lithium Electrolysis Optimisation Plant (CLEOP) at Industriepark Höchst. Since November, it has been converting lithium chloride from production in Landau into battery-ready lithium hydroxide monohydrate (LHM). The first commercial plant is to be built once the process has been optimised. This would make Vulcan the first producer in Europe to completely close the production chain for the manufacture of LHM from European lithium. The first quantities from the optimisation plant will be sent to the battery and automotive industry for validation, including Stellantis, Renault, LG and Umicore. Further pilot projects for geothermal lithium extraction are already being planned in Hesse.
A new technology from the US company Lilac Solutions could lead to progress in lithium extraction. It is said to be able to extract more than 90 per cent of lithium from brine. The company is trying to win customers around the world for this technology. The technology uses ion exchange ceramic beads to extract the lithium in batch cycles and then wash it out again.
Also AMG Bitterfeld is already able to deliver
AMG (Advanced Metallurgical Group) reached a milestone in September 2024: in Bitterfeld, the company commissioned the first of five modules of its lithium hydroxide refinery, the first in Europe capable of producing 20,000 tonnes of lithium hydroxide per year for around 500,000 electric cars. The other modules could go into operation by 2030. With a potential production of 100,000 tonnes of lithium hydroxide, AMG would hold around 14 percent of the forecast European market. However, AMG extracts the raw material, the lithium mineral spodum, from a mine in Brazil. Nevertheless, the company would make a significant contribution to security of supply in Europe.
More lithium refineries to be built in Finland, Slovakia and the UK
Europe's second lithium refinery is scheduled to go into operation in Kokkola, Finland, in 2026. Locally extracted spodumene concentrate will be processed there. The plant is part of the Keliber project, part of Sibanye-Stillwater. Up to 15,000 tonnes of battery-grade lithium hydroxide could be produced there in the future. The commissioning of a lithium refinery (Volt Resources) in Slovakia and in the UK (Green Lithium) has also been announced for 2026. The latter is designed for a production volume of around 50,000 tonnes of lithium hydroxide per year.
Imerys is also pressing ahead with the Emili project in France, initially focussing on further environmental impact studies. A new location for the loading centre is being examined. Reduced use of chemicals is also promised in order to convince the public of the sustainability of the project. By the end of the decade, the company wants to start mining lithium at the Beauvoir site in central France and in Cornwall, UK.
Will Spain also become a lithium producer?
In contrast, the start of lithium production in Spain is uncertain. The company Extremadura New Energies is planning to mine in the Extremadura region. However, authorisation for the project is still pending - and is meeting with considerable resistance. As in Serbia, it is questionable whether it can ever be realised.
Concrete production sites are therefore still few and far between - and not all planned projects will go into operation as planned. Nevertheless, the variety and number of projects shows how actively Europe is working on supplying the growing electromobility sector with lithium hydroxide - and largely self-sufficiently from European supply chains.
May 2024: Lithium from Europe – first milestones reached
Lithium is one of the key raw materials for a successful mobility transition. To date, it has mainly been extracted in South America, Australia, and China. However, there are also deposits in Europe, for example as a component of granite. The first mine owners are already planning the production chain from mining to conversion to lithium hydroxide. European lithium from thermal water is already a reality.
Since the EU has been focussing more on self-sufficiency in the critical raw material lithium, a number of new mining projects have been created. Often, the production facilities for lithium hydroxide, which is needed for battery production, are also being planned. European lithium could be available from Portugal in the foreseeable future, for example. In May 2023, the Portuguese environmental authority APA approved the environmental impact assessment of a lithium mine near Covas do Barroso in northern Portugal. Large lithium deposits have been found in the German-Czech border region near Cinovec and Zinnwald. There are also lithium deposits in Extremadura in Spain, Carinthia in Austria, the Upper Rhine in south-west Germany and Alsace in France, Serbia and Ukraine that are suitable for large-scale mining.
A French project for the extraction and integrated production of lithium for batteries is currently making particularly substantial progress. Imerys, a manufacturer of speciality minerals for industry, confirmed at the end of January 2024 that the planned conversion plant will be built in La Loue in the French department of Allier. In future, lithium hydroxide is to be extracted from lithium-containing mica from the nearby Beauvoir quarry.
Large-scale production of French lithium hydroxide from 2028
In future, the company will be able to produce up to 34,000 tonnes of lithium hydroxide per year in the conversion plant, a quantity that should be sufficient to equip 700,000 electric vehicles with batteries per year. The Emili project (EMILI = Exploitation de MIca LIthinifère par Imerys; mining of lithium-containing mica by Imerys) includes all production steps from extraction to lithium production. The total investment framework amounts to one billion euros. Initially, a demonstration plant r around 400 tonnes of lithium hydroxide per year is to be built. The commercial plant is scheduled to be commissioned in 2028.
According to Imerys, all steps - from mining the lithium-containing granite to the production of mica as a suspension and the production of lithium hydroxide for batteries - are as close together as possible. Lorries transport the mica to the plant in La Loue. After calcination, it is dissolved and purified. The lithium hydroxide is then crystallised. The product is in powder form.
On the border between Germany and the Czech Republic near Dresden, the infrastructure of an old tin mine is to be used. The mining of zinnwaldite containing lithium is planned from 2028 at the earliest. Lithium from old tin mines near Dresden
The fact that the high demand for lithium can even breathe new life into industrial wastelands is proving true in the German-Czech border region. Under the villages of Zinnwald and Cinovec near Dresden lies the second largest hard rock lithium deposit in the EU and the third largest in Europe, totalling over 2.6 million tonnes of lithium carbonate equivalent (LCE). This is in the form of the ore type Zinnwaldite. The project planners at Zinnwald Lithium are assuming an annual production of 12,000 tonnes of lithium hydroxide. The mine could therefore be utilised for at least 35 years, with parts of the existing underground infrastructure of the Altenberg tin mine being reused. In the best-case scenario, the project will be extended to several neighbouring areas. Mining of the deposit is scheduled to begin in 2028 at the earliest.
The distinctive feature of this project is that the extracted ore is to be mined underground over several kilometres to the processing plant. A concentrate is extracted from Zinnwaldite, which is considered more environmentally friendly than the more commonly used spodumene ore, by crushing, grinding and magnetic separation. This is calcined, i.e. made water-soluble by roasting in a rotary kiln. Water leaching produces a solution with a high lithium content. After precipitation of the potassium sulphate, it also contains, lithium carbonate is produced, which is converted into battery-grade lithium hydroxide. The by-products are also to be marketed, e.g. as a fertiliser and as a paper filler. Partner Metso in Finland is currently evaluating the process on a pilot scale.
Austrian lithium for further processing in Saudi Arabia
There are also promising lithium projects in Austria, particularly advanced in Wolfsberg (Carinthia). European Lithium is responsible for exploration there. According to European Lithium, spodumene, the primary lithium-bearing material, may be mined as early as 2025. The quantities mined should be sufficient for up to 10,000 tonnes of lithium hydroxide per year. However, according to several Austrian sources, it will be further processed into battery-grade lithium in Saudi Arabia.
Vulcan started producing climate-neutral lithium chloride in April. It is produced from geothermal brine from the Upper Rhine Graben and is further processed into lithium hydroxide at Industrie Park Höchst in Frankfurt. Green brine lithium from Landau - in parallel with deep geothermal energy
Lithium extraction in the German Upper Rhine Graben has gone one step further. At the end of November, the company Vulcan Energy Resources inaugurated the first lithium extraction plant (LEOP) on a tonne scale in Landau, Palatinate. The process has already been optimised in two pilot plants. Unlike the aforementioned mining projects, lithium is extracted in Landau from deep groundwater containing lithium salts (brine) using a sorbent developed by Vulcan. In this way, Vulcan Energy Resources aims to massively reduce the carbon dioxide footprint that is often associated with the extraction of lithium. At the same time, a geothermal power plant is to be created, i.e. renewable energy is to be extracted in addition to lithium.
The so-called lithium extraction optimisation plant (LEOP) is regarded as the preliminary stage of a commercial plant. Lithium chloride is produced here for further processing in Frankfurt's Höchst Industrial Park. The CLEOP (Central Lithium Extraction Optimisation Plant) is being built there for this purpose. It is scheduled to go into operation in summer 2024. It will use electrolysis to convert lithium chloride solution into lithium hydroxide monohydrate (LHM). This is further processed through raw and pure crystallisation and drying. The lithium hydroxide is to be used for pre-qualification tests. The by-product hydrogen chloride is sold at the chemical park.
A commercial plant is then planned, which will produce 24,000 tonnes of LHM for around 500,000 car batteries per year. In total, the lithium produced in the Upper Rhine Graben will be sufficient for up to 400 million electric vehicles.

The various European projects are helping to establish European value chains for the supply of lithium to the battery industry. This contributes to security of supply on the one hand and sustainability on the other. Not only the project at Vulcan in Landau, but also the other projects in Europe contribute to reducing the environmental impact. Transport routes involved in lithium extraction in remote locations such as the Atacama Desert in Chile can be radically shortened. It is also assumed that European lithium production will generally be significantly more energy-efficient than in Chile or China. Other environmental impacts can also be better controlled and regulated here. The European extraction and production of battery-grade lithium therefore offers opportunities to sustainably improve the ecological footprint of lithium batteries.
