Types segmentation for natural quartz sand is organized around grain‑size distribution, purity grade, and geological source, each influencing end‑use suitability and price differentials. Grain‑size classification—coarse (0.5–2 mm), medium (0.2–0.5 mm), and fine (<0.2 mm)—determines packing density and flow characteristics; coarse sand predominates in concrete aggregates, while fine sand is essential for glass melting and casting molds. Purity grades are divided into high‑purity (≥99 % SiO₂) and standard (≈95–99 % SiO₂); high‑purity sand commands a premium due to reduced processing for glass and semiconductor applications, whereas standard sand serves broader construction needs. Geological source—river, desert, and beach deposits—introduces variability in mineral contamination and particle shape; river sand typically offers rounded grains with lower feldspar content, desert sand provides angular particles but may contain higher iron oxides, and beach sand often requires desalination. The relative market share of these type sub‑segments aligns with application demand, where high‑purity fine sand from river sources dominates the glass segment, and coarse standard sand from desert or river beds fuels construction volumes, thereby structuring the overall market taxonomy.
