Source Category Survey: Borax and Boric Acid Industry

In the borax acidulation process, which is used by both U.S. Borax and Stauffer, a hot saturated borax solution or finely granulated borax is reacted with sulfuric acid in an acidifier or digester. When the solution is cooled in vacuum crystallizers to the appropriate temperature, crystalline boric acid precipitates.

US3656891A - Process for the production of potassium

Glaserite and sylvite are digested in the presence of borax in a metathesis reactor at a temperature above the crystallization temperature of borax to form a borax free potassium sulfate precipitate and a metathesis liquor containing borax. Residual potassium values in the metathesis end liquor are converted to glaserite by sulfate ion addition for recycle to the metathesis reactor.

Overview - Borax Pentahydrate

Borax obtained from lake brines, tincal, and colemanite is separated from the constituent salts. The hot liquor obtained is consisted of borate and potassium salt (KCl). To remove the potassium salt, the insoluble solid particles are filtered out and the hot liquor is cooled in continuous vacuum crystallizers under controlled conditions of temperatures and concentration to crystallize KCl.
