Mining Technology and Construction Consultancy Wins Hanoi Pilot to Target 95%+ Rare-Earth Oxides

Highlights

• Mining Technology and Construction Consultancy JSC is running an 18-month semi-industrial pilot processing Dong Pao ore at 100 kg per hour.
• The pilot targets 95%+ total rare-earth oxide using flotation, leaching, purification, and calcination, tracked across 33 KPIs.
• Output cannot be sold during the trial and scale-up economics remain unknown, making recovery rates and reagent intensity the key metrics to watch.
• Vietnam plans to pursue light rare-earth separation after the pilot, signaling ambition to move further up the value chain.
• The process aims to recycle over 80% of hydrometallurgical water and recover barite, fluorite, and sodium fluorosilicate byproducts.
