WSP feasibility study paves the way for UK rare earths supply

The feasibility study was informed by process trials taking place at a demonstration plant that Ionic Technologies is currently operating in Belfast, which it says is the “first in the Western world”.

The demonstration plant produces recycled separated magnet rare earth oxides using a proprietary technology developed by Ionic Technologies at Queen’s University Belfast and acquired in 2022.

The new commercial facility, designed by Ionic Technologies and WSP with input from the British Geological Survey and Innovate UK, would increase capacity fortyfold compared with the demonstration plant.

Subject to regulatory approvals and project funding, construction of the commercial plant is expected to be completed in late 2026 and be operational in early 2027.

Rare earth elements

Rare earth elements are essential to decarbonise the economy because they are used in green technologies such as wind turbine generators and electric vehicles.

The International Energy Agency estimates demand for them could increase to 169,000 tonnes annually by 2040.

Although they are relatively abundant in the Earth’s crust, rare earth elements are difficult to extract and process as it is unusual to find them in a pure form.

China produces almost 90% of the world’s refined rare earth oxide supply. The Chinese government has been restricting exports of key critical raw materials, including antimony, and this year it declared that rare earths are state property.

To avoid reliance on Chinese exports, the EU and the US have initiated efforts to procure rare earths at home and abroad, including Brazil, Vietnam and Australia.

However, processing infrastructure can take years to set up and is unlikely to scale up in Europe or the UK at sufficient speed to reduce risks of disruptions before 2030, according to a paper by the Oxford Institute for Energy Studies.

Moving rapidly

In 2022, the government published the UK’s first ‘critical minerals strategy’ to develop a supply rare earth minerals supply chain and strengthen the industries depending on them.

Commenting on the commercial plant feasibility study, Andrew Woodward, head of industry at WSP, said: “Rare earths are critical to the future of the net-zero energy transition, and this milestone reflects our shared commitment to designing for a sustainable future and achieving net zero together.”

Brett Lynch, executive chair of Ionic Technologies’ parent company, Australian-based IonicRE, said: “This feasibility study demonstrates that IonicRE is leading the field in the race to develop a supply of rare earth oxides outside China using net-zero carbon technologies.

“Our Belfast plant is the first producer of recycled separated magnet rare earth oxides in the Western world. We are now moving rapidly to commercialise rare earth recycling, with planned commercial-scale production within just two years, offering investors direct exposure to the growth of a Western supply chain.”
