U.S. Silica's Kosse plant mines sand and kaolin clay from the "Simsboro Sand," a white to light gray, fine to coarse grain, cherty sand suspended in a white clay matrix. Sand mined from the Kosse facility is used primarily for the glass and recreational sand industries, with a small portion of sand sold as grout sand. The kaolin clay is sold to the paint industry and for brick production.

The Kosse location has a rich history that is centuries old. Settlers once dug pottery clay from Kosse's outcroppings and used its ore to make firebrick. In 1964, a mining plant was constructed and due to the growing industrialization in the surrounding area, the mining and processing complex was an immediate success. Today, the Kosse plant produces and ships high-quality minerals to customers throughout the world.


Kosse employees are involved in many community activities from volunteer fire departments to cancer fundraisers. The plant itself makes sand donations, in addition to contributions to many educational programs and local organizations.
