Clean pegmatite feldspar rocks alongside 200-800 mesh bagged powder for export.
High-Purity Feldspar (K & Na)
Ultra-Low Iron (Fe₂O₃ < 0.08%) | K₂O > 11.5% / Na₂O > 9.5% | Ceramic & Glass Grade | Lump & Micronized Powder
ELMAGD MINERALS offers premium-grade Potassium Feldspar (K-Feldspar) and Sodium Feldspar (Na-Feldspar) harvested from world-class pegmatite deposits. Our feldspar is renowned for its ultra-low ferric oxide content (Fe₂O₃ < 0.08%), outstanding fluxing power, and exceptional whiteness upon firing (L* > 88). Available both as washed calibrated lumps (10–80 mm) and micronized powder (200, 325, 500, and 800 mesh), it provides superior vitrification, chemical stability, and optical clarity for high-end ceramics, porcelain tiles, tableware, sanitaryware, and photovoltaic glass.

Have Low-Grade Feldspar Ore?
Feldspar Beneficiation & Magnetic Separation Plant
Beyond exporting certified high-purity feldspar lumps and powders, ELMAGD MINERALS designs and manufactures complete Turnkey Feldspar Beneficiation Plants. Using Wet High-Gradient Magnetic Separation (SLon Vertical Ring) and scrubbing circuits, we reduce Fe₂O₃ to below 0.05% — producing super-white ceramic and glass-grade concentrates from run-of-mine ores.
Magnetic separation & scrubbing line reducing Fe₂O₃ below 0.05% for ceramic-grade feldspar.
