Yuncheng pond salt

Produced in Yuncheng, Shanxi. Sodium sulfate, sodium chloride and magnesium sulfate are the main resources in the salt lake, with a total reserve of more than 83.7 million tons. Bromine, calcium, iodine, potassium, boron, lithium, plane, strontium, gallium, rubidium and other rare elements are also abundant. There is also a kind of mirabilite coexisting with salt, namely, glauberite, which is mainly composed of double salts of sodium sulfate and magnesium sulfate, with a thickness of 2-4 meters and a storage of more than 16 million tons of ore bodies exposed to the surface. This is a unique and precious resource formed after thousands of years of salt production by predecessors.
