Procedure

Miller, in U.S. Pat. No. 3,264,057, discloses a process for producing soda ash crystals by leaching carbonate values from crude trona and decomposing the major part of sodium bicarbonate in the resulting solution by steam stripping at about 110° C. Miller also discloses in U.S. Pat. No. 3,246,962 a method for obtaining concentrated solutions of sodium carbonate and sodium bicarbonate from crude mined trona by leaching the alkali values from crude trona in a column while passing steam into the column.
