What is Soda Ash? - Industrial Minerals Association ...

12.07.2019  A series of refining steps are required to produce soda ash from trona ore. First the raw ore from the mine is crushed and screened. The materia l is then fed to rotary calciners and heated. In this process, the trona decomposes to form crude soda ash, which is dissolved in water. The insoluble shales are separated from the solution by a combination of settling and
