Critical Mineral Exploration & Extraction
Laos possesses world-class deposits of Rare Earth Elements uniquely concentrated within ion-adsorption clay deposits across northern and central provinces.
End-to-End Rare Earth Consulting
Focusing on weathered ionic-adsorption clay deposits rich in Heavy Rare Earth Elements (HREEs) such as Dysprosium and Terbium, alongside LREEs like Neodymium and Praseodymium.
Geological Assessment & Profiling
Regolith Horizon Mapping
Systematic auger and shallow diamond core drilling to accurately define boundary layers between the upper red soil, ionic-adsorption saprolite layer, and unweathered bedrock.
Sequential Chemical Extraction
Specialized laboratory leaching tests using ammonium sulfate extraction at controlled pH to isolate true ion-exchangeable REEs from unrecoverable mineral-bound fractions.
Leaching Engineering & Hydrometallurgy
In-Situ Leaching (ISL) Design
Optimized well grids introducing weak electrolyte solutions directly into the saprolite layer, coupled with robust groundwater containment barriers.
Heap / Pool Leaching Optimization
Surface containment pool leaching systems using ion-exchange mass transfer techniques, utilizing oxalic acid or ammonium bicarbonate circuits.
Environmental Safeguards & Remediation
Tailings & Filtrate Neutralization
Robust neutralization washing phases to purge residual ammonium ions from treated soils, preventing soil acidification.
Water Recycling
Closed-loop hydrometallurgical systems that reclaim and reuse up to 90% of process water and electrolyte chemicals, minimizing fresh water intake.
