Sodium Sulfate an editing method for preparing (beach field method) use of natural raw material type of seasonal temperature changes in the water solution was evaporated and the crude crystallized Glauber. Summer saltwater containing sodium chloride, sodium sulfate, magnesium sulfate, magnesium chloride and other ingredients poured salt field, Sodium Sulfate evaporated by the sun, winter precipitation crude Glauber. This method is the main method of thenardite made from natural resources, the process is simple, low energy consumption, but poor working conditions, the product easy to mix sediment and other impurities. Method 2 (mechanical freezing) using mechanical equipment heating the raw material liquid was evaporated to -5 ~ -10 ℃ frozen precipitation when thenardite. Compared with the salt field method, this method is not affected by seasonal and natural conditions. Good quality, but high energy consumption. Method three (Salt Lake utilization method) is mainly used for sulfate containing a variety of components - carbonate salt water. In a variety of useful components from the extract, separating the crude mirabilite. Such as processing with sodium carbonate, sodium sulfate, sodium chloride, boride and potassium, bromine, lithium, sodium sulphate salt lake water Haihua, Salt Lake Brine carbonation can be so converted into sodium bicarbonate crystallized; cooling the mother liquor to 5 ~ 15 ℃, so borax crystallized; secondary mother liquor after separation of borax chilled to 0 ~ 5 ℃ Shandong Weifang sodium sulphate precipitation Glauber.
