  • The Process to Recover Soda Ash from Mining

    The process to recover soda ash from mining solution is combined CO2 stripping with falling film evaporation, and the stripping operation is the key step in the process, the processing installations include a CO2 stripping tower, falling film evaporators and other accessoriesSolution Mining When conventional underground mines become flooded and unworkable, soda ash can be extracted using solution mining Water is injected as a brine or salt and water solution It is then circulated throughout the mine workings to dissolve soda ash and salt from the original pillars and walls The brine is pumped to an evaporation pondITP Mining: Energy and Environmental Profile of the US
