Abstract
Disclosed herein is a method for treating an alkaline brine. The method comprises adding a source of magnesium ions to the alkaline brine. A resultant magnesium-containing precipitate is separated to produce a spent brine. If the spent brine contains a sufficient amount of carbonate or bicarbonate ions, the spent brine is processed to recover a carbonate product.
