U.S. Silica's Dubberly plant produces fine grain silica from a mineral resource known as the "Sparta" Formation. The Sparta consists primarily of loose, unconsolidated, fine to coarse, light-colored sand intermingled with light-colored clays, which is processed for the glass, chemical, roofing, brick and foundry industries.

Since acquiring the facility, we renovated and upgraded its production capabilities to enable it to produce multiple products through various processing methods, including screening, washing, fluid bed drying and conditioning to remove heavy and iron-bearing minerals. 

Dresser Industries carried out an extensive exploration program during the summer of 1970, which resulted in the discovery of the South Dubberly deposit. Dresser Industries operated the facility until it was purchased by Ottawa Silica Company in July 1981, which merged into the U.S. Silica family in 1987.

The facility is located approximately 30 miles east of Shreveport and is accessible by major highways including U.S. Interstate 20 and state Highway 532. 


Dubberly employees strive to be exemplary members of their community and to preserve the environment in which they operate. Their efforts include land reclamation and recycling process water. Additionally, they volunteer through local fire departments, youth activities and local service organizations.
