Olivine sand does not have the tensile strength of silica but produces no harmful dust. Olivine sands are no longer mined in the United States so, at least in North America, this is no longer the primary source of foundry sand. Silica. Ferrous foundries (those dealing with iron and steel) usually use silica sand, sometimes known as quartz sand.
