Why is Wyoming natural dense soda ash used for lithium carbonate extraction?

Precipitating dissolved lithium from brine into battery-grade lithium carbonate demands tight chemical purity. Wyoming natural ash is typically specified at NaCl ≤0.20% and iron ≤20 ppm.

What is the physical difference between dense and light soda ash in glassmaking?

Chemically, dense and light soda ash are identical sodium carbonate (≥99.2% Na2CO3). Physically, dense ash has a bulk density of 0.95–1.05 g/cm³ with coarse granules, matching silica sand grain size in glass furnaces. Light ash (0.50–0.60 g/cm³) is fluffy and easily swept away by furnace burners, attacking regenerative refractory bricks. Glassmakers use dense ash exclusively.

How is bulk soda ash loaded and protected from moisture caking in ocean transit?

Dense soda ash is carried under the IMSBC Code schedule for soda ash. Because sodium carbonate is hygroscopic, loading is suspended in rain, and cargo holds must be dry and kept closed during the voyage to prevent crusting.

What commercial payment terms apply to international soda ash shipments?

Cargoes are contracted on FOB Columbia River, CFR, or CIF liner terms, settled via 100% Irrevocable Documentary Letter of Credit (L/C) at sight (UCP 600) against presentation of clean on-board Bills of Lading, Certificate of Origin, and SGS load-port draft survey and assay certificate.

US Natural Soda Ash Export Gateway

310,372 tonnes of dense natural soda ash (Na2CO3 ≥99.2%, NaCl ≤0.20% typical) exported by vessel in July 2026, loading at Columbia River berths for South American and Asian buyers

The Green River Basin of southwest Wyoming contains the world's largest known deposit of bedded trona ore (sodium sesquicarbonate). Unlike synthetic Solvay or Hou-process soda ash produced in Europe and China, which consume more energy and generate large volumes of calcium chloride effluent, Wyoming natural soda ash is refined from mined trona.

US trade data record 310,372 metric tonnes exported by ocean vessel in July 2026 valued at USD 62.1 million ($200.09/MT average). Unit trains haul soda ash from Green River to Columbia River export berths: Port of Longview Berth 2 (43 ft / 13.11 m draft) and Port of Portland Terminal 4 (40 ft / 12.19 m draft). Argentina took 75,371 MT, India 39,362 MT, Malaysia 31,029 MT, Chile 25,850 MT and Brazil 23,132 MT. Soda ash is used to precipitate lithium carbonate from lithium chloride brine (2LiCl + Na2CO3 -> Li2CO3 + 2NaCl) and as a flux in glassmaking.

CBIL brokers bulk dense natural soda ash for battery chemical refiners, glassmakers, and detergent formulators. CBIL is a commodity brokerage: each lot is brokered between a named seller and a named buyer against SGS or Alfred H Knight pre-shipment certification of chemical purity (Na2CO3 ≥ 99.2%, Total Alkalinity as Na2O ≥ 58.0%), chlorides (NaCl ≤0.20% typical), iron (Fe2O3 ≤ 20 ppm), and bulk density (0.95–1.05 g/cm³), executed on FOB Columbia River, CFR, or CIF delivery terms under 100% Irrevocable Documentary Letter of Credit.
