Magnesium chloride can be divided into white tablets and ordinary tablets according to product quality. White tablets mainly refer to magnesium chloride produced by acid process, which is white in color, transparent and free of impurities. Acid process is prepared by the reaction of hydrochloric acid and magnesium oxide; Common tablets refer to magnesium chloride produced by the big pot boiling process, which is generally milky white or brown in color. The big pot boiling process is divided into big equipment and local cooking. The process of common tablets uses saturated brine. Some of the brine here uses seawater to extract magnesium chloride directly from seawater, which requires large equipment. In addition to the acid method and boiling method, there are also natural halogen crystals in Qinghai, which are mined directly from underground.

Magnesium chloride can be divided into industrial grade magnesium chloride and food grade magnesium chloride according to its use. Industrial grade magnesium chloride is widely used in users' metallurgical industry, chemical industry, building materials and machinery industry. Food grade magnesium chloride is mainly used as protein coagulant and food additive. We often say "brine point tofu" is also magnesium chloride.
