Ottawa, IL


U.S. Silica's Ottawa plant is North America's largest silica production facility, mining fine grain, nearly pure quartz sandstone from the St. Peter Sandstone deposits. Ground and unground silica products from the Ottawa facility have a wide variety of applications, including glass production of all kinds, foundry and refractory sand, abrasives, polishes, paint and other fillers, filtration sand, frac sand, and cement testing sands.


Silica sand mining began in Ottawa in the 1860s. At that time in Ottawa, glass manufacturing was one of the most important industries and the silica sand and glass manufacturing businesses grew simultaneously. The Ottawa facility became part of the U.S. Silica family in 1987, and succeeds in continually improving its processes, products and services, making them the leading producer of silica products, with an annual production rate of 2.2 million tons of silica annually.


Ottawa employees volunteer their time and talents to many benevolent activities, such as youth programs and charitable foundations and boards.

The Ottawa plant maintains a high standard of environmental compliance and awareness. The property is a sanctuary for numerous species of wildlife. Therefore, the organization has contracted with "Pheasants Forever," a nonprofit conservation organization, in an effort to perpetuate the preservation of the "Upland" wildlife existing on the property.
