Soda ash also plays a crucial role in water treatment, pH regulation, and even food processing. 1. Glass Manufacturing. One of the most notable applications of soda ash is in the production of glass. As a fluxing agent, soda ash reduces the melting point of silica (the main component of glass) during the glassmaking process.

No matter what they are called, the calciner plays a critical part in the soda ash production process. The calciner is used to heat the trona ore to around 300 – 350º F. Heating to this temperature drives off CO2 and some water to yield soda ash that can be further processed into a more pure form. Once trona ore has been processed, the now ...
