About 30% of world soda ash production (90% of this is in U.S. alone) is from natural deposits and the rest 70% from synthetic process. Soda ash is a white, finely crystalline, hygroscopic powder. When freshly packed, contains at least 98.5% Na2CO3. It absorbs moisture and carbon dioxide from the atmosphere during storage and transit.

Soda Ash is a key component in the production of powdered detergents and soaps due to its high alkalinity and surfactant qualities, which allows it to improve the solvency, and the effectiveness, of the detergent in removing stains whilst using less water. Soda Ash is used in the mining and smelting of various metals, especially alumina products.

Soda ash, also known as sodium carbonate (Na 2 CO 3) is currently a leading product in chemical industries around the world. The name 'soda ash' is based on the principal historical method of obtaining alkali which was by using water to extract it from ashes. Several sources yielded soda ash. Among these, are the barilla plant in Spain, ashes of Kelp in Scotland and alkali mined from dry ...
