A Saskatchewan group is breaking floor as the primary to commercially produce uncommon earth metals in North America.
The Saskatchewan Analysis Council (SRC) first achieved the feat over the summer season when it extracted neodymium praseodymium (NdPr) from a mineral referred to as monazite. The group plans to interrupt into the Chinese language-dominated market as soon as its facility is totally operational subsequent 12 months.
“The rationale this isn’t taking place everywhere is as a result of it’s actually arduous to do,” stated Jeremy Harrison, the provincial minister accountable for the SRC treasury board crown company.
For many years, China has realized the worth of uncommon earth metals — a set of 17 components on the periodic desk — which might be key parts within the digital world and utilized in every thing from cell telephones to electrical autos (EVs).
NdPr powers the strongest sort of uncommon earth magnets utilized in EVs. The fabric is sort of fully outsourced from China, which controls about 90 per cent of the uncommon earths market, in response to the SRC.
“Previously two years, there was plenty of curiosity outdoors of China to develop this sector,” stated Muhammad Imran, the SRC’s vp of uncommon earth components.
At instances, China makes use of its stronghold as leverage to drive international coverage, in response to Heather Exner-Pirot, the director of vitality, pure sources and surroundings on the Macdonald-Laurier Institute.
In December 2023, China positioned an export ban on its uncommon earths processing applied sciences.
“They’re consultants on it. They’re leaders on it, and so they don’t desire anybody else to have the ability to diversify,” Exner-Pirot stated.
China has been capable of good the know-how wanted to commercially course of these components, partially as a result of nation’s lax environmental and labour legal guidelines.
“It may be a unclean job. It may be a tough job,” Exner-Pirot stated.

The job entails working with excessive warmth to smelt metals, which is why the SRC has enlisted the assistance of synthetic intelligence to deal with a number of the labour.
“We needed to de-risk this. We didn’t need to create radically new processes which might introduce threat. We needed to make use of current processes, however function them loads smarter,” stated SRC president Mike Crabtree.
After months of tinkering with the AI know-how, the SRC can course of 10 tonnes of NdPr every month. By the tip of 2025, the group hopes to course of 400 tonnes yearly, a provide that can assist manufacture 500,000 EVs.
Earlier this 12 months, the SRC together with Ottawa, bought a stockpile of uncommon earths that got here from a mine close to Yellowknife. They had been initially slated to be offered to a Chinese language firm.
“What we wish is that worth to remain right here in Canada moderately than being exported. So we need to play a key function in initiating that offer chain predominantly for North America,” Crabtree stated.
Exner-Pirot stated any tip within the scales will assist diversify the market.
“Any time you’ll be able to cut back China’s leverage out there, it will be general web optimistic. So getting them from 90 per cent dominant to 85 or 80 per cent dominant, that every one helps in decreasing their leverage,” she stated.
Uncommon earths capabilities attain past EVs. Canada’s competitiveness inside the market is necessary for nationwide defence, too, Crabtree stated.
The SRC has plans to finally course of the uncommon earth samarium, a key ingredient in defence weapons, reminiscent of F-35 fighter jets.
Crabtree stated the ability might course of sufficient samarium required for 25 per cent of North America’s defence weapons.
