As a commodity, the term silica is applied to quartz in all its forms — as vein or reef quartz, quartz pebbles, sandstone, quartzite, or as unconsolidated sand. World consumption approximates 120 Mt/year. Quartzite, sand and gravel used for construction purposes are excluded from this category.
3. Used as a foundry sand. Quartz sand may be incorporated with other materials to form a material that can be used in metal casting and molding. For example, quartz sand can be mixed with oil, clay, and resin sodium silicate. In metal casting, Quartz qualifies to be used because it has a high melting point and's strong.
Sand is used in buildings, roads, toothpaste, glass, desktop screens, as a water purifier, and even for natural oil and gas extraction. While sand is, in theory, a renewable resource, the formation of sand and gravel from rock is a process that takes millions of years. The United Nations reports that sand mining is a $70 billion industry.
