## Minestarters Atlas summary

AE Fuels has successfully completed mini-pilot testing conducted by CSIRO, achieving manganese recoveries of 95-99%. The program demonstrated continuous purification and the production of battery-grade high-purity manganese sulphate monohydrate \(HPMSM\) crystals.

Reasoning: The mini-pilot testing successfully demonstrated high manganese recovery and the production of battery-grade crystals under continuous operating conditions, representing a significant technical de-risking milestone.

- Positive factor: High manganese recovery \(95-99%\)

- Positive factor: Successful production of battery-grade HPMSM crystals

- Positive factor: Continuous mini-pilot testing demonstrated scalability

- Positive factor: Strong impurity control \(calcium, magnesium\)

Facts used in scoring: 1

## Classification and evidence

**High Recovery**

Polarity: positive

Definition: Recovery at or above the exceptional band for the commodity and processing route.

Why it applies: Manganese recovery of 95-99% is exceptional for this processing route.

Evidence · text

> manganese recoveries ranging from 95% to 99%

**Free Milling**

Polarity: positive

Definition: Simple, clean ore amenable to standard processing without oxidation.

Why it applies: The release describes successful purification and crystallization of manganese sulphate liquor without mentioning refractory issues.

Evidence · text

> The purification circuit demonstrated strong impurity control

**Mill Route**

Polarity: neutral

Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\).

Why it applies: The process involves a continuous purification circuit and crystallization.

Evidence · text

> continuous purification performance

## 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.
