Tata Chemicals North America (TCNA) has been mining and processing trona ore, a mineral that contains soda ash, at Green River, Wyoming since 1968.
Wyoming has the world's largest deposit of trona, supplying about 90% of the nation's soda ash. This mineral is Wyoming's top export and is shipped to markets around the globe. Wyoming mines produced over 17 million tons of trona and employed 2,483 people in 2015.
The trona near Green River, Wyoming, is the largest known deposit in the world and lies in layered evaporite deposits below ground, where the trona was deposited in a lake during the Paleogene Period.
Abstract. Bedded trona (Na 2 CO 3 ·NaHCO 3 ·2H 2 O) in the lacustrine Green River Formation of Eocene age in the Green River Basin, southwest Wyoming, constitutes the largest known resource of natural sodium carbonate in the world. In this study, 116 gigatons (Gt) of trona ore are estimated to be present in 22 beds, ranging from 1.2 to 11 meters (m) in thickness.
