processing of silica quartz in Mexico

Silica Statistics and Information | U.S. Geological Survey

Industrial sand and gravel, often called "silica," "silica sand," and "quartz sand," includes sands and gravels with high silicon dioxide (SiO 2) content. These sands are used in glassmaking; for foundry, abrasive, and hydraulic fracturing (frac) applications; and for many other industrial uses.

High Silica and Quartz

The term high silica can be used to describe any high-purity glass. However, for use in reinforced plastics, we shall define high silica as a high-purity glass of 95%-plus punty SiO 2 produced by a leaching process. High-silica fibers and fabrics are flexible materials that are similar in appearance to—and produced from—fiberglass.
