About Quartz (Lumps)
Quartz lumps are crystalline silicon dioxide minerals extracted through open-pit mining, primarily used in glassmaking, foundry molds, abrasives, and silica refractories for high-temperature industrial applications. International trade focuses on lump grades sorted by size (typically 10-100mm) and silica content purity (98-99.8% SiO2 required for premium applications). Major producers include Brazil, Norway, Madagascar, and the United States, with significant exports from Southeast Asia and India. Buyers should verify true silica purity through certified laboratory analysis rather than relying on supplier claims, as iron oxide and alumina impurities significantly impact performance in glass and refractory applications.
