Industrial sand and gravel, often called "silica," "silica sand," and "quartz sand," includes sands and gravels with high silicon dioxide (SiO2) content. These sands are used in glassmaking; for foundry, abrasive, and hydraulic fracturing (frac) applications; and for many other industrial uses. The specifications for each use vary, but silica resources for most uses are

Mineral: Silica sand can be used as a type of mineral abrasive. It tends to break up quickly, creating large quantities of dust, exposing the operator to the potential development of silicosis, a debilitating lung disease. To counter this hazard, silica sand for blasting is often coated with resins to control the dust.
Silica sand, a natural raw material, is an important component in the production of recyclable glass containers—a core element of the G3 commitment to sustainability. The sand is also used for top dressing and bunker sand in golf courses, bedding in horse arenas, and surfaces in community parks.
Silica Sand Processing Machinery. The raw materials for processing silica sand generally are extracted from open pits of naturally occurring quartzrich sand and sandstone. The mined rock is transported to the processing site. The material then is crushed.
Dec 10, 2010· About a half a mile down the road, there is a small sandblasting/plumbing business that occasionally sandblasts outside, creating lots and lots of dust. I only see this when driving down the road, but I am concerned about the harmfulness of the dust in the air due to my familiarity with silica and silicosis (and due to me being a little bit of a hypochondriac).

Silica Sand is actually a granular material. It contains quartz and minute amounts of coal, clay. Sometimes it has minerals in it. People call it quartz sand too. Most importantly it is the industrial sand. Quartz over time turns into Silica sand gradually because of the influence of water and wind.
Silica Gel, SiO2, is essentially a synthetic, microporous form of sand. It's produced in small, irregular beads that contain thousands of microscopic cavities. These cavities create a low vapor pressure inside it, which makes the beads hygroscopic...
Silica sand is growing in demand because it is ideal for the oil and gas hydraulic fracking boom that is spreading across the country. A hydraulic fracturing job on one well can require a few thousand tons of sand. This sand is used to prop open the fractures made in the rock, allowing petroleum to flow out of the rock and into the well.
