Trona (trisodium hydrogendicarbonate dihydrate, also sodium sesquicarbonate dihydrate, Na 2 CO 3 ·NaHCO 3 ·2H 2 O) is a non- marine evaporite mineral. [4] [6] It is mined as the primary source of sodium carbonate in the United States, where it has replaced the Solvay process used in most of the rest of the world for sodium carbonate production.
Trona, an evaporite mineral, hydrated sodium bicarbonate [Na3H (CO3)2·2H2O], 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.
Trona is a sodium carbonate compound that is processed into soda ash or bicarbonate of soda, or baking soda, as it is commonly known. Wyoming has the world’s largest deposit of trona, supplying about 90% of the nation’s soda ash.

The geography and geology of Lake Magadi is such that it is among the few places on earth where trona (a naturally occurring mineral that contains sodium carbonate compounds) can be found at the surface. Lake Magadi occupies a trough in the Great Rift Valley of East Africa.
Nov 14, 2023 · The world’s largest deposit of trona is in the Green River Basin of Wyoming. Trona also occurs in California, the Nile Delta of Egypt, Kenya, Namibia, and Turkey. Trona is mined by room and pillar, longwall, and in-situ solution mining," the United States Environmental Protection Agency says.
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.
