The tests demonstrated significant enrichment capabilities, such as 280x germanium enrichment and the ability to convert raw REE ore into a high-purity chloride product. Reasoning: The company demonstrated high-value recovery and enrichment across a diverse range of critical metal feedstocks using its proprietary FJH technology. - Positive factor: Successful demonstration of proprietary technology across multiple distinct feedstocks - Positive factor: Significant enrichment factors reported for germanium and REE - Positive factor: High selectivity in red mud processing \(99% Fe removal\) - Positive factor: Single-cycle PGM recovery from catalytic converters - Negative factor: Testing results are described as 'unoptimized' - Negative factor: Technology is proprietary and likely at a bench or pilot scale rather than commercial scale Facts used in scoring: 9 ## Classification and evidence **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: The technology involves processing mineral concentrates and waste streams through a proprietary heating process.
