Trona. Columnar, fibrous and massive. 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 ...
Aug 29, 2024 · 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
Aug 24, 2024 · Trona is a naturally occurring mineral extensively utilized in the cosmetics industry due to its antioxidant and skin-protecting qualities. The mineral’s impressive antioxidant capabilities extend to neutralizing harmful free radicals, which are unstable molecules that can damage cellular structures and contribute to premature skin aging.
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.

Lake Magadi Kenyan rift valley. 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.
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.
Wyoming trona, a lacustrine evaporite of Eocene Age, is mined by five producers which process over 90% of the United States and 20% of the worlds soda ash. Total world consumption of soda ash is forecast to grow 1% annually.
Trona Na3(CO3)(HCO3)•2H2O. Crystal Data: Monoclinic. Point Group: 2/m. Crystals are dominated by {001}, {100}, flattened on {001} and elongated on [010], with minor {201}, {301}, {211}, {211}, {411}, to 10 cm; may be fibrous or columnar massive, as rosettelike aggregates.
Trona, hydrated sodium bicarbonate carbonate (Na 3 HCO 3 CO 3· 2H 2 O), is an evaporite mineral. 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.
