Using this method, which can significantly conserve fosil fuels over other methods, all of the compounds listed in Table 15 can be obtained. The six principal compounds listed in order of their solubility are: sodium chloride, sodium sulfate, potassium sulfate, magnesium sulfate, potassium chloride, and magnesium chloride. In the solar evaporation process, brine is pumped or allowed to flow into a large shallow pond. When evaporation has increased its density to cause the mineral to precipitate, the remaining |
