Flotation testwork also demonstrated the ability to produce a large-flake concentrate \(over 50% flake content\) at 94% carbon purity. Reasoning: The confirmation of a cost-effective, high-purity purification route \(99.96% LOI\) without pre-heating is a significant de-risking milestone for commercial scale-up. - Positive factor: High purity \(99.96% LOI\) achieved via a simple two-stage alkaline process - Positive factor: Avoidance of energy-intensive pre-heating step - Positive factor: Retention of large flakes \(>50%\) during flotation - Positive factor: Successful purification of oxidized historical stockpiled material - Negative factor: Testwork conducted on oxidized historical material which may underperform compared to fresh ore - Negative factor: Initial flotation performance was below expectations Facts used in scoring: 4 ## Classification and evidence **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: Testwork utilized VeRoLiberator milling equipment and flotation. Evidence · text > Woxna ore was processed using VeRoLiberator® \("VeRo"\) milling equipment ## Extracted facts Stored fact records: 4.

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.
