Biogenic silica - Wikipedia

Biogenic silica (bSi), also referred to as opal, biogenic opal, or amorphous opaline silica, forms one of the most widespread biogenic minerals.For example, microscopic particles of silica called phytoliths can be found in grasses and other plants. Silica is an amorphous metal oxide formed by complex inorganic polymerization processes. This is opposed to the other major biogenic minerals ...

Silica Statistics and Information - USGS

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

Oil sands are actually found all over the world, and are sometimes referred to as tar sands or bituminous sands. A typical oil sands deposit in Alberta contains on average about 10% bitumen, 5% water and 85% solids, mostly in the form of coarse silica sand. Oil sands also contain fine solids and clays, typically in the range of 10 to 30% by weight.
