## Minestarters Atlas summary

Renascor Resources has successfully produced battery-grade purified spherical graphite \(PSG\) with 99.97% carbon purity at its Adelaide demonstration plant. This milestone validates the company's hydrofluoric acid-free purification process at a demonstration scale, moving beyond laboratory-scale testing.

Reasoning: The company successfully transitioned its HF-free purification technology from laboratory scale to a demonstration plant, achieving high-purity battery-grade graphite.

- Positive factor: Successful demonstration scale production of battery-grade graphite

- Positive factor: Achieved high purity of 99.97% carbon

- Positive factor: Validation of HF-free \(hydrofluoric acid-free\) purification process

- Positive factor: Demonstration plant results support customer engagement and offtake potential

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: Achieved 99.97% carbon purity, which is exceptional for battery-grade graphite processing.

Evidence · text

> The company achieved 99.97% carbon purity through an integrated circuit

**Mill Route**

Polarity: neutral

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

Why it applies: The process involves an integrated purification circuit including leaching and roasting.

Evidence · text

> RNU’s process combines sulphuric acid leaching with a low-temperature caustic roast.

**Single Domain Only**

Polarity: negative

Definition: 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.
