Alkemy to build Australia's first lithium sulfate plant at Port Hedland

Published by , Deputy Editor
Dry Bulk,

Alkemy Capital Investments plc will build a lithium sulfate plant at Port Hedland, Australia’s largest export port located in the Pilbara region of Western Australia, to feed the Tees Valley Lithium Ltd (TVL) lithium hydroxide (LHM) plant at the Wilton International Chemicals Park, Teesside, UK.


  • Alkemy to build lithium sulfate (LSM) plant at Port Hedland, in the Pilbara region of Western Australia, to serve as a refining hub for Australian miners.
  • Port Hedland hosts the largest bulk export port in the world and the largest container port in Australia.
  • The Pilbara is a major spodumene producing region and centrally located near existing and planned spodumene producers in Australia.
  • Port Hedland LSM plant production will supply the expansion of TVL’s Wilton LHM facility, with Train 1 set to produce 24 000 tpy of battery-grade LHM from 2024.
  • Port Hedland LSM plant will offer Australian spodumene producers mid-stream processing options with direct access to the premium European battery market.
  • Port Hedland LSM plant will export a higher-grade, lower-volume product resulting in less tonnage shipped and less transport carbon emissions.

Alkemy announces a plan to build an LSM plant at Port Hedland in the Pilbara region of Western Australia.

Train 1 of the Port Hedland LSM plant is set to process spodumene from Australian lithium miners to produce 40 000 tpy of primary LSM, with Trains 2 – 4 adding a further 120 000 tpy primary LSM production in future expansions.

The Port Hedland LSM plant, together with TVL’s planned LHM processing facility at the Wilton International Chemicals Park in Teesside, UK, will deliver a low carbon, de-risked lithium supply chain between Western Australian spodumene producers and the burgeoning European lithium battery cell market.

Alkemy and TVL Director, Sam Quinn, commented: “Alkemy is delighted to announce its plans to develop the Port Hedland LSM plant.

“Working with leading global metals trader, Traxys, to source the spodumene feedstock for the Port Hedland LSM plant, Alkemy is now progressing discussions to finalise and secure the optimal site for the Port Hedland LSM plant and the definitive spodumene feedstock agreement to underwrite the development of the plant.

“Building the Port Hedland LSM plant will provide Australian spodumene producers with a complete mid-stream refining solution with direct access to the Euro-pean market.

“Importantly, it will also bring major downstream processing and value adding to the Pilbara region of Western Australia, with significant multiplier benefits for the local community, whilst reducing the carbon footprint of the end to end lithium battery cell supply chain to meet new European emissions standards.”

Supply partnership

Alkemy and its wholly-owned subsidiary, TVL, recently announced a supply agreement with leading global physical trader and merchant in metals and natural resources, Traxys North America LLC, a member of the Traxys Group of companies.

Alkemy and TVL are partnering with Traxys to source and supply lithium feedstock for TVL's LHM processing facility in the UK.

This partnership with Traxys will also encompass the sourcing and supply of spodumene concentrate to the Port Hedland LSM plant for Train 1.

The Traxys partnership will offer existing and new Australian spodumene producers the opportunity to supply their spodumene concentrate to a merchant mid-stream LHM refining solution through TVL's Port Hedland primary LSM plant in Australia and the Wilton LHM plant in the UK.

Based on market feedback to date, this offering is expected to be most attractive to Australian spodumene concentrate producers as it will provide them with:

  • Direct access to the premium European lithium battery gigafactory market.
  • Downstream processing capability in Australia at no capital cost.
  • Ability to reduce net carbon emissions in the lithium battery cell supply chain by lowering the volume of material transported to downstream refining capacity.
  • Lower overall delivered costs of spodumene to customers by reducing transport distances and volumes.

More than 700 GW of lithium battery gigafactories are planned for construction across Europe, which will require over 325 000 tpy of LHM from 2030.

Currently, there is no LHM production capacity in Europe or the UK.

Approximately half of the carbon footprint of a lithium battery cell is from the mining and transport of the lithium raw materials in the battery cell.

Major battery cell manufacturers have stated publicly that the best way to reduce the carbon footprint of battery cell production is to reduce the volume of raw materials shipped around the world by refining lithium raw materials prior to shipping.

Alkemy has identified Port Hedland as the optimal site for the proposed new LSM plant for a number of key reasons:

  • Proximity to existing and planned spodumene producers in the Pilbara.
  • Well located for the import of spodumene production from other parts of Australia for conversion to primary LSM prior to export to the UK.
  • Access to critical infrastructure, including skilled labour, road, power, gas, water and telecommunications.
  • Adjacent to world's largest bulk export port and Australia's largest container port.
  • Ability to source renewable energy and energy storage from new developments planned in the region, delivering the new LSM plant with low carbon energy sources.

Alkemy has commenced discussions with relevant Western Australian Government agencies regarding an appropriate site for the planned Port Hedland LSM plant.

At this stage, Alkemy expects the plant to be located at a site close to Port Hedland.

Downstream processing of Australian critical mineral production is a key focus of the Australian Federal Government and the Western Australian State Government and Alkemy is very appreciative of the support already expressed by government agencies for the Port Hedland LSM plant.

Construction of Train 1 of TVL's LHM processing facility at the Wilton International Chemicals Park in Teesside, UK, the first of four trains planned for the site, is due to commence at the end of this year.

Initial production of 24 000 tpy of battery-grade LHM is planned for 2024. Once completed, all four trains will produce a total of 96 000 tpy LHM, representing around 15% of Europe's projected demand by 2030.

By sourcing low carbon primary LSM from the Port Hedland plant and powering an electrochemical process with offshore wind, TVL is aiming to supply its customers in Europe and the UK with the world's lowest-carbon LHM.

Alkemy also confirms that 100 000 options have been issued to consultants on the same terms as set out in the company's RNS dated 4 August.
