When using magnesium sulfate monohydrate, pay attention to its chemical properties. Sometimes, artificial or environmental factors such as improper storage will cause agglomeration, which will affect the use of the product, so we must promptly To avoid the factors of agglomeration.

Magnesium sulfate monohydrate uses hematite slag as raw material. The process of hot acid leaching is mainly based on the potential-pH of several metals. It is difficult to separate zinc from iron during acid leaching because it is necessary to ensure that ferric ions enter the solution. The purification stage is mainly based on the removal of metal compounds based on the different pHs of Fe and Zn, Mn, Mg, Cu, etc.

The reduction is to reduce Fe3 to Fe2 to achieve the final purpose of obtaining Fe2 ions. The crystallization is achieved by using different saturation and further removes impurity metal ions. The pH is controlled to be relatively low. At this time, zinc ions also enter the solution, thereby Zinc cannot be separated, so it causes agglomeration of magnesium sulfate monohydrate.

镁 Magnesium sulfate monohydrate easily forms lead sulfate, and the solubility of lead sulfate in the acid is very small. Therefore, in the acid leaching process, the pH should be controlled at a lower level.
