Minestarters Atlas analysis
Summary
Brazil Potash announced positive initial results from AI-powered X-ray Transmission (XRT) sorting testwork at the Autazes Project. The testing demonstrated the ability to upgrade potash grade from 13% to 27% KCl and reject approximately 20% of lower-grade material, offering potential for increased production or extended mine life.
Reasoning: Initial XRT sorting testwork showed significant grade upgrading and waste rejection potential, though scale remains a risk.
Positive factors
- Successful upgrading of KCl grade from 13% to 27%
- Potential to reject 20% of lower-grade material before processing
- Potential to increase production or extend mine life
Negative factors
- Small sample size makes results indicative rather than representative
- Technology implementation is subject to further large-scale testing
Facts used in scoring: 2
Classification and evidence
Bench Scale Onlynegative
Only preliminary bench tests completed — no locked-cycle or pilot work.
Why it applies: The company notes the results are based on a small sample and are indicative, not representative of full-scale production.
Evidence · text
“Due to the small sample tested, the results are indicative and cannot yet be regarded as representative of full-scale mine production.”
Mill Routeneutral
Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
Why it applies: The technology is intended to preconcentrate material before reaching the processing plant.
Evidence · text
“could be screened out before reaching the processing plant”
Multi-Domain Testedpositive
Variability across ore domains (oxide, transition, fresh) has been addressed.
Why it applies: 2 distinct composites were tested

Reasoning: The rejected fraction shows low grade, confirming the sorting effectiveness.
Positive factors
- Effective rejection of low-grade material (1-2% KCl)
Evidence · text
“the rejected fraction contained approximately 1% to 2% KCl”
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.
