Quartz Lumps – 100–600 mm (M-Grade)
Description:
The M-Grade Quartz Lumps form the foundation of all industrial quartz processing. These large, naturally occurring lumps exhibit a milky-white crystalline structure with occasional brown or iron oxide inclusions — a signature of naturally rich deposits. With typical SiO₂ purity above 98%, this grade is ideal for crushing and downstream manufacturing.
Applications:
- Raw material for refractories, foundries, and glass plants
- Feedstock for silica sand and engineered stone
- Used in metallurgical flux and ceramic applications
Quality Highlights:
- High mechanical strength
- Naturally low moisture content
- Uniform chemical composition
