Green River facility
Tata Chemicals North America (TCNA) has been mining and processing trona ore, a mineral that contains soda ash, at Green River, Wyoming since 1968. The Green River facility is located on the "mile-high" prairies of southwestern Wyoming, home to the world's largest reserves of trona ore. Here, more than 60 billion tons of trona can be found extending over
1,000 square miles at depths of up to a third of a mile.
TCNA's manufacturing facility consists of an underground trona mine and a surface refining plant that processes the ore into soda ash. The facility is located about 40 miles west of Rock Springs and 175 miles northeast of Salt Lake City. It operates around the clock, seven days a week, 365 days per year.
The company mines more than 4.5 million tons-per-year of trona ore.
The estimated recoverable trona ore reserves consist of approximately
600 million tons, enough to provide approximately 100 years of reserves based on current operating rates.
The mine has an underground tunnel network spanning 20-plus square miles. Personnel and equipment enter the mine via a hoist that descends the 1,600 feet to the mine in two-and-a-half minutes. Open four-wheeled vehicles provide transportation throughout the mine and to the production faces.
