Carnallite, a complex salt mineral rich in potassium, magnesium and chlorine, has attracted worldwide attention for its unique chemical composition and diverse industrial applications. This rare mineral resource, with its rich uses, provides valuable raw materials for several key areas of modern society. Firstly, Carnallite plays a vital role in the production of magnesium metal. As an important raw material for extracting magnesium metal, Carnallite can effectively release magnesium through thermal decomposition or electrolysis process. Magnesium metal is widely used in the aerospace industry to manufacture lightweight aircraft and satellite components because of its lightweight and high-strength properties. In the automotive industry, magnesium alloys are used to manufacture automobile body and engine components to reduce vehicle weight and improve fuel efficiency. At the same time, magnesium is also an important material in the electronic and electrical industry, which is used to manufacture enclosures and components of electronic devices. Carnallite therefore provides the global magnesium industry with a wealth of natural resources and plays an integral role in supporting the development of these key industries. Secondly, Carnallite is one of the main sources of potassium chloride. Potassium chloride, as a common inorganic fertilizer, contains potassium needed for plant growth and is essential for improving the yield and quality of crops. At the same time, potassium chloride is also the basic raw material for many chemical industries and is used to produce various chemical products. Through advanced extraction technology and mineral treatment processes, potassium chloride can be efficiently extracted from Carnallite to meet the needs of agriculture and industry. In addition, the chemical diversity of Carnallite gives it a wide range of applications in the manufacture of inorganic compounds. For example, it can be used to produce compounds such as magnesium oxide and magnesium chloride, which have important applications in construction materials, refractories, medicine, environmental protection and many other fields, and are key elements supporting the operation of modern industrial societies. It is worth mentioning that the hygroscopicity and ion exchange properties of Carnallite make it have certain application value in the field of industrial hygroscopicity and water treatment. In the chemical industry, food processing and other industries, Carnallite as a desiccant can effectively remove water in the air and materials to keep the production environment dry; In water treatment, it can help remove hardness ions in water and improve water quality, which is of great significance for the protection and utilization of water resources. As a natural multifunctional mineral, Carnallite plays an important role in magnesium production, fertilizer industry, inorganic chemical manufacturing and water treatment. With the continuous progress of science and technology and the in-depth study of resource utilization, the potential value of Carnallite will be further explored, and its application prospect in the future industrial development will be broader.
