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. [9] Trona has also been mined at Lake Magadi in the Kenyan Rift Valley for nearly 100 years.
Aug 29, 2024 · trona, an evaporite mineral, hydrated sodium bicarbonate [Na 3 H (CO 3) 2 ·2H 2 O], occasionally encountered as a saline lake deposit or evaporation product and as an efflorescence on arid soil. Usually associated with natron, thermonatrite, halite, and gypsum, it occurs near Memphis, in the Lower Nile Valley; widely in the soda lakes of ...

The deposition of trona in Wyoming started about 50-60 million years ago during the Eocene Age in the Wilkins Peak Member of the Green River Formation. A large freshwater lake, Lake Gosiute, covered an estimated 15,000 square miles in a basin in southwestern Wyoming. The lake was fairly shallow and evaporated rapidly and repeatedly creating a clima...
All trona is mined underground and then processed into soda ash or baking soda. An underground trona mine is like an underground city. There are maintenance shops, bathrooms, electricity lines, and streets. Most trona is mined through a room-and-pillar system where a series of parallel drifts are driven. Connections are made between the drifts at r...
In the 1st century, the Romans used soda ash for making bread, glass, and medicine, uses which continue today. Baking soda and baking powder both come from soda ash, so most Americans have a product of Wyoming trona right in their own kitchens. These two common household substances are important ingredients for making bread, cookies, cakes, and oth...
Wyoming hosts the world's largest trona deposits, an estimated resource of 127 billion tons. Of this, 40 billion tons are mineable using conventional “hard rock” methods. Trona, or natural soda ash, is a sodium sesquicarbonate compound that occurs as an evaporite mineral in the Wilkins Peak Member of the Eocene Green River Formation in ...
United States, trona is mined in China, Turkey, Africa, and Mex-ico. The largest known trona deposits in the world are in south-western Wyoming in the Wilkins Peak Member of the Green River Formation. The layered trona deposits range in depth from 800 to 2,200 feet below the surface. Known as “bedded trona,”

The continued decline In the production of synthetic soda ash (sodium carbonate) due to high costs and associated environmental factors, has improved the world demand for natural soda ash. The largest resource of natural soda ash is the mineable trona deposits of Southwestern Wyoming. Wyoming trona, a lacustrine evaporite of Eocene Age, is mined by five producers which process over 90% of the ...
