The process achieved an average eluate lithium concentration of >3,100 mg/L and demonstrated high impurity rejection using sulfuric acid. Reasoning: The pilot testing successfully demonstrated the ability to produce high-purity battery-grade lithium carbonate from brine with high concentration and impurity rejection using low-cost reagents. - Positive factor: Successful production of battery-grade lithium carbonate \(>99.95% purity\) - Positive factor: High lithium concentration in eluate \(>3,100 mg/L\) - Positive factor: Excellent impurity rejection \(>99%\) - Positive factor: Use of low-cost sulfuric acid for desorption - Positive factor: QA/QC protocols disclosed including use of AGAT Laboratories and standard reference materials - Negative factor: Pilot scale testing \(not commercial scale\) Facts used in scoring: 6 ## Classification and evidence **High Recovery** Polarity: positive Definition: Recovery at or above the exceptional band for the commodity and processing route. Why it applies: Achieved >98% lithium recovery during pilot testing. Evidence · text > successfully achieved >98% lithium recovery **QA/QC Disclosed** Polarity: positive Story-specific tag Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: Release mentions use of standard reference materials, duplicates, and AGAT Laboratories. Evidence · text > standard reference material was used on a regular basis as well as duplicate samples ## Extracted facts Stored fact records: 6.

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.
