Strategic Rare Earths
The core elements of the high-tech frontier. Supplying premium Light and Heavy Rare Earth Elements (LREE/HREE) engineered for global permanent magnet, aerospace, and energy storage manufacturing sectors.
The Magnetic Engine of Tomorrow.
SINCHI WAYRA SA holds a strategic position within the critical minerals supply chain. We process and export high-purity rare earth materials, ranging from rich Monazite and Bastnäsite concentrates to highly refined Mixed Rare Earth Oxides.
Our Super High-Grade Concentrates (50–70% TREO) are engineered specifically for major Asian chemical converters and magnet manufacturers. By strictly controlling radioactive elements like Thorium and Uranium, we guarantee rapid China Customs clearance, superior chemical conversion efficiency, and optimized NdPr extraction.

Beneficiation & Chemical Conversion
1. Mining & Beneficiation
Raw monazite, bastnäsite, and xenotime ores are extracted and milled for fine mineral liberation. Advanced froth flotation, magnetic, and gravity separation circuits are deployed to dramatically increase the TREO concentration while managing silica and iron impurities before packaging.
2. Chemical Conversion Reactions
Our concentrates undergo sophisticated chemical pathways to isolate individual REEs (like Nd, Pr, Dy, Tb):
- Acid Leaching: RE2O3 + 3H2SO4 → RE2(SO4)3 + 3H2O
- Carbonate Formation: RE2(SO4)3 + 3Na2CO3 → RE2(CO3)3 + 3Na2SO4
- Oxide Calcination: RE2(CO3)3 → RE2O3 + 3CO2
Powering Permanent Magnets & Defense.
From the extraction of critical elements to the delivery of premium concentrates to the largest refiners in China, Japan, and South Korea, SINCHI WAYRA SA provides an unbroken, high-purity supply chain for the world’s most critical strategic technologies.
