Superior Silica Sands is a leading supplier of high-quality frac sand available in North America. With three dry plants locat ... ed in Wisconsin and over 5mm TPY of premium northern white sand along with a vast network of transload facilities across the US and Canada, we strive to provide the customer with the highest level of quality and customer service possible. The genesis of Superior Silica Sands is our Kosse, TX mine and dry plant. Upon the acquisition in June 2008, SSS' Kosse plant has transformed into a 600,000 TPY plant. Kosse's portfolio of products includes a high quality 40/140 frac sand along with an abundant mix of non-frac, industrial style sand, allowing Kosse to supply multiple industries including agriculture, golf courses, filtration and hydraulic fracturing with a product you can trust. With over 80mm tons of reserves, 900,000 TPY of current capacity, located at the heart of the Eagle Ford is SSS' newly acquired dry plant and mine in San Antonio, TX. This facility is currently undergoing a construction upgrade to include a full-scale 3.7mm TPY of exceptional local 40/70 and 100M frac sand. Like Kosse, San Antonio also offers a wide range of non-frac, foundry and industrial sands.
