uipments used soda ash production process

Baking soda, or sodium bicarbonate, comes from soda ash obtained either through the Solvay process or from trona ore, a hard, crystalline material. The Manufacturing Process. Soda ash can be manufactured chemically using the Solvay process, or it can be made from trona ore. If trona ore is used, it must first be mined.

Glass Manufacture –Soda ash is an important ingredient in the manufacture of glass, since it helps reduce silica'smelting point. Other Applications –Soda ash is also a common addition to spa and pool treatment chemicals helping in reducing the acidity in water.

VARIOUS CHEMICAL PROCESSES PRODUCTION OF SODA ASH (1) Le Blanc Process This process was invented by Nicolas Le Blanc, a French man,who in 1775, among several others submitted an outline of a process for making soda ash from common salt, in response to an offer of reward by the French academy in paris.

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.
