Soda Ash, also be called sodium carbonate (Na2Co3), it is a alkali chemical redined from the mineral trona or naturally occurring sodium carbonate-bearing brines (both referred to as natural soda ash), the mineral nahcolite ( referred to as natural sodium bicarbonate, from which soda ash can be produced), or manufactured from one of several chemical processes.

A series of refining steps is required to produce soda ash in trona. First, the mine’s ore is crushed and screened. The material is then fed to a rotary calciner and heated. In this process, the trona decomposes to form the crude soda ash, which dissolves in water. The insoluble shale is separated from the solution by a combination of sedimentation and filtration steps and the resulting insoluble tailings are recovered as feed back to the mine. The soda ash solution is treated to remove the organic material that produces a high purity sodium carbonate saturated solution.

Next, the solution is fed to a crystallizer, where water is evaporated and forms a sodium carbonate monohydrate crystal. The industry-familiar term “single process” is derived from this process step. The crystals were dewatered and washed with a cyclone and a centrifuge, and the solution was recycled to the evaporator unit to further recover soda ash. The monohydrate crystals are fed into a rotary kiln where they are dried to complete soda ash. Finally, the product is screened and sent to the warehouse waiting for track and truck loading and unloading.

Soda has some variety of uses that touch our lives every day. Glass is made of both the production of containers, glass fiber insulation materials, or for the housing, commercial and automotive industry, the largest application of flat glass, soda ash.

Soda is also used to clean the air and soften moisture. With the growth of environmental problems, the demand for soda from the removal of sulfur dioxide and hydrochloric acid from flue gas is increasing. Chemical producers use soda ash as an intermediate to make sweet soft drinks (corn sweeteners) that reduce body discomfort (sodium bicarbonate), improve food and cosmetics (phosphate). Household detergents and paper products are other common examples of easy-to-identify products that use soda ash.
