Summary
Aclara announced completion of a conceptual engineering study for its rare earths separation project, developed with Saskatchewan Research Council and based on solvent extraction. The company said the concept achieves over 99.5% purity and expected recoveries of 94% for NdPr, 92% for Dy and 91% for Tb, while estimating initial CAPEX of US$354 million and OPEX of US$12/kg REO. It also said it will continue with trade-off chemistry, location analysis and metallurgical testing/optimization.
Reasoning: The release reports a conceptual engineering study and preliminary flowsheet results for a rare earth separation project, which is materially positive but still early-stage and not yet optimized.
Positive factors
- Completion of a conceptual engineering study for the REE separation project
- Expected metallurgical recoveries of 94% for NdPr, 92% for Dy and 91% for Tb
- Uses solvent extraction technology with hydrochloric acid chemistry
- Initial CAPEX and OPEX estimates were provided
Negative factors
- Study is conceptual and the release describes the CAPEX and OPEX as unoptimized
- Next steps still include bench scale and mini-pilot testing
- No project location for the contemplated separation facility was stated
Facts used in scoring: 3
Classification and evidence
Mill Routeneutral
Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
Why it applies: The release states that the separation flowsheet concept is based on solvent extraction and uses hydrochloric acid chemistry.
Evidence · text
“The separation flowsheet concept, based on solvent extraction”
High Recoverypositive
Recovery at or above the exceptional band for the commodity and processing route.
Why it applies: Expected recoveries of 94% for NdPr, 92% for Dy and 91% for Tb are strong outcomes for the separation concept.
Evidence · text
“Expected metallurgical recoveries of 94% for NdPr, 92% for Dy and 91% for Tb.”
Single Domain Onlynegative
Testing limited to one composite or domain — representativeness not established.
Why it applies: only one composite was tested

How Atlas produces this analysis
Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
