ABSTRACT:
A method for recovering alkali values from subterranean deposits of trona ore associated with sodium chloride by contacting the trona with an aqueous mining solution containing sodium hydroxide and subsequently utilizing the alkali values contained in the resultant salt- and sodium carbonate-containing solution. The alkali values are preferably crystallized as substantially salt-free sodium carbonate monohydrate, which is dried to recover soda ash. The mother liquor containing all of the salt is then treated to prepare a dilute sodium hydroxide solution, which may be employed as aqueous mining solution in a cyclic method to recover additional alkali values from trona.
