Wyoming facilities use one of two processes to refine soda ash from trona ore: (1) the monohydrate process or (2) the sesquicarbonate process. The two processes are essentially the same, differing only in the sequencing of procedures. The monohydrate method is the primary process used today to make soda ash. In addition to these two …
