A problem with their production has been that the potash content is always weak (usually only about 1–2% KCl), and thus a solar evaporation, or expensive plant evaporation step, was first required. Also, the brines always contain many other ions, thus complicating the separation of potash from the evaporated brine or crystallized salts.
