bauxite deposits for bayer process . bauxite deposits for bayer process. If you want to get more detailed product information and prices, ZME recommend that you get .
In the Bayer process, the alumina and the silicate clays initially dissolve in the caustic soda solution. Sodium in the caustic soda then combines with reactive silica to produce the residue red mud waste, which falls out of the solution taking the sodium with it. The loss of sodium represents a significant cost.
