On the earth, salt is mainly divided into four categories: sea salt, well salt, mineral salt and lake salt. Each of them has different characteristics and production sites.
The production of sea salt is mainly concentrated in coastal areas, using seawater to evaporate the water with the help of sunlight and wind, and the salt is left behind. Sea salt is relatively cheap to produce, so it is also cheaper and is the most common type of salt. There is large-scale production of sea salt in many countries around the world, such as China, the United States, India, etc.
Well salt is a salt that is extracted from underground brine by drilling wells and refining it through processing. The production areas of well salt are mainly concentrated in Sichuan, Hubei, Hunan, Shaanxi and other regions. The quality of well salt is higher and there are fewer impurities, so it is also relatively high.
Mineral salts, on the other hand, are mined from underground rocks and are usually formed during the movement of the earth's crust. The production areas of mineral salt are mainly concentrated in Europe, North America and South America. The quality of mineral salt is also higher, slightly lower than well salt.
Lake salt, on the other hand, refers to salt extracted from inland saltwater lakes, usually by drying salt directly or by evaporating the lake water. The production cost of lake salt is higher, so it is also relatively high. The world's famous lakes and salt producing areas include the Great Salt Lake in the United States, Lake Chad in Africa, etc.
In addition to the above four main types of salts, there are some other types of salts, such as volcanic rock salt, rock salt formed by green plants, etc. These salts vary in quality and use, but in general, they are among the most salts on the planet.
In short, there are many places on the earth where salt is produced, and the quality of salt varies from one to the other. As people's concerns about food quality and health continue to increase, so does the demand for different types and qualities of salt. Therefore, understanding the characteristics and uses of different salt is of great significance for us to choose the right salt and ensure the quality of food.
