Minestarters Atlas analysis
Summary
Mount Ridley Mines has reported successful metallurgical test results for its Selectro™ program, achieving 91.8% scandium recovery. Notably, the recovery was achieved using half the reagent required previously and operated at atmospheric pressure on unbeneficiated ore.
Reasoning: The announcement reports high scandium recovery using significantly reduced reagent consumption at atmospheric pressure, which is a strong positive signal for processing economics.
Positive factors
- High scandium recovery (91.8%)
- Reduced reagent consumption (half the reagent)
- Atmospheric pressure leach (lower complexity/capex)
- Tested on unbeneficiated ore
Facts used in scoring: 1
Classification and evidence
High Recoverypositive
Recovery at or above the exceptional band for the commodity and processing route.
Why it applies: 91.8% scandium recovery is reported, which is exceptionally high for a leach process.
Evidence · text
“reports 91.8% scandium recovery”
Mill Routeneutral
Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
Why it applies: The test used atmospheric pressure leaching on unbeneficiated ore, implying a standard hydrometallurgical route.
Evidence · text
“best recoveries at atmospheric pressure, on unbeneficiated ore”
Single Domain Onlynegative
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.
