How to handle magnesium sulfate mother liquor correctly

Mother liquor, commonly known as bittern, is a saturated solution that remains after separating precipitates or crystals during the chemical precipitation or crystallization process. (Feed additive magnesium sulfate) Magnesium sulfate mother liquor, as the name suggests, is the remaining saturated solution of magnesium sulfate after the reaction is completed. How should magnesium sulfate mother liquor be treated? Let's take the production of boric acid as an example to introduce it to everyone.

The technical scheme adopted for the mother liquor of ammonium sulfate produced by the sulfuric acid method is to treat the mother liquor of magnesium sulfate produced by the sulfuric acid method by the following process: first, the mother liquor is heated to 95-100 ℃, and solid ammonium sulfate is added in an appropriate amount to the mother liquor. The weight ratio of ammonium sulfate and magnesium sulfate is 1:1-1.4:1, allowing it to dissolve and react to generate magnesium ammonium sulfate. The generated solution is filtered, cooled, and crystallized to precipitate magnesium ammonium sulfate, Perform drying treatment.

This method can extract over 80% magnesium sulfate from the mother liquor without concentrating it, accelerating production speed, saving coal and electricity, and reducing costs; Compared with the traditional concentration method, the amount of mother liquor processed has been reduced by half, saving equipment; At the same time, it greatly reduces the loss and environmental pollution caused by boron volatilization with steam during the concentration of mother liquor; By using this method, a large amount of low-grade boron ore can be fully utilized, and the processed ammonium magnesium sulfate is also a good nitrogen magnesium sulfur fertilizer in agriculture.

Magnesium sulfate is currently widely used, including food additives and feed additives. Magnesium sulfate has good development prospects and is a trustworthy product for everyone. The above is all about how to properly handle magnesium sulfate mother liquor, hoping to be helpful to everyone.
