Magnesite Lump Rock
Coarsely crushed natural magnesite in lump form (typically 6-150mm), directly from mining operations without beneficiation. Crushing is a mechanical process permitted under Chapter 25 notes, and the product remains natural magnesium carbonate.

Brazilian Compact Magnesite
Dense, compact natural magnesite from Bahia, Brazil, valued for its high bulk density and low porosity in refractory applications. It is a natural magnesium carbonate in the crude or crushed state, not subjected to processing beyond that permitted by Chapter 25 notes.
Chemical Grade Magnesite Powder
Micronized natural magnesite ground to 10-50 micron particle size for fertilizer and chemical applications. The grinding process is a mechanical or physical process permitted by Chapter 25 notes, and the product retains its full MgCO3 composition without chemical change.
Chinese Magnesite Concentrate
Flotation concentrate from Liaoning, China, typically 94% MgCO3 with controlled silica content. The flotation process is a physical concentration method allowed under Chapter 25 notes, and the product remains natural magnesium carbonate.
Dead-Burn Refractory Magnesite
Large-particle natural magnesite (2-6mm) used directly as a soil amendment in agriculture to supply magnesium and neutralize acidity. It is unprocessed beyond crushing and sizing, which are permitted mechanical processes under Chapter 25 notes.
Floatation Grade Magnesite
Beneficiated magnesite concentrate from froth flotation, achieving 95%+ MgCO3 purity while remaining chemically unchanged natural carbonate. Froth flotation is a physical separation process explicitly allowed under Chapter 25 notes.
Greek Magnesite Ore
Premium cryptocrystalline magnesite from Kozani, Greece, known for 97% MgCO3 purity and low impurities. It is a natural magnesium carbonate in its crude state, not processed beyond mining and sorting.
