Silica, Crystalline (Respirable Size) Properties

01/07/1990 Silica sand deposits, commonly quartz or derived from quartz, typically have a silica content of 95%; however, impurities may be present at up to 25%. Silica sand has been used for many different purposes over many years. In some instances, grinding of sand or gravel is required, increasing the levels of dust containing respira- ble crystalline silica. Sand with low iron content and more than
