refined quartz sand ，It has a colorless, transparent, or semi-transparent block-like structure, and its color is uniform and pure, without impurities. The processing of refined quartz sand is particularly complex, involving mechanical crushing and multiple manual color selection to refine the mineral particles.

Main Uses of Refined Quartz Sand:
Production of stone slabs: Refined quartz sand can be used to produce high-quality slab sands. It is also a processing material for manufacturing quartz slabs and marble slabs.
Coatings and paints: Due to its high silica content, refined quartz sand can be added to coatings and paints to improve their weather resistance.
Filtration media for wastewater treatment: Refined quartz sand can be used as an industrial water treatment and filtration media. Its high silica content and low impurities contribute to a longer lifespan compared to ordinary quartz sand.
