Soda Ash: A Critical Industrial Raw Material
Soda Ash Soda Ash, also known as sodium carbonate, is an inorganic salt that appears as a white, crystalline powder or solid. It has the chemical formula Na2CO3 and is mainly obtained by extracting trona ore from underground deposits or synthesizing it from salt and limestone. With a wide array of industrial applications, sodium carbonate serves as an important raw material for the glass, chemical, detergent and other major industries worldwide. Extraction and Production of Natural Sodium carbonate Over 90% of the world's natural sodium carbonate deposits are found in the United States. The largest underground reserves exist in Wyoming in massive deposits of trona. Trona ore predominantly contains sodium sesquicarbonate and is extracted through conventional underground mining techniques. The crushed ore is then calcined at high temperatures to thermally decompose it into sodium carbonate and water vapor. The processed sodium carbonate is then screened, dried and prepared for Globa...
