Silica sand — particularly the grains mined in North America — is typically found inland, deep under the earth's surface, left behind by ancient glacier movements. In almost all cases, silica sand is mined using an open-pit or dredging method, effectively digging large holes to remove sand or scooping it from lake and river beds.
