Sea salt is actually the salt extracted from seawater. On average, 27 kilograms of salt can be produced per 1000 kilograms of seawater, accounting for 80% of the national salt production. However, with the increasing demand for salt purity, the output of sea salt is getting lower and lower. This is mainly because there are many impurities in sea salt. If you want to improve the purity, you need to spend a lot of energy to complete it. In addition, there is a great demand for sea salt sites, and there are few suitable sites to complete the production of sea salt.

However, compared with lake salt, it has a large production area and less pollution around it, which is more convenient to extract high-purity salt, which also ensures the quality of salt. In addition to less impurities and good quality, lake salt also contains all kinds of natural minerals, which can greatly enhance its taste, ensure the salty taste is mellow, and bring more benefits to the body. The above is the difference between sea salt and lake salt, so it is better to choose lake salt compared with sea salt.

Resource reserve of lake salt

Qinghai is known as the world with salt. Among them, Chaerhan Salt Mine, which is well-known at home and abroad, has 43 billion tons of stone salt reserves, accounting for 97% of the country's total reserves. It is an important chemical raw material and is used for food. The content of sodium chloride is more than 96%, which has the characteristics of pure salt flavor. According to its color, there are green salt, white salt, red salt and black salt.

There are pearl salt, glass salt, coral salt, crystal salt, snowflake salt, vermicelli salt, mushroom salt, stalactite salt, pagoda salt and so on. Green salt can also be artificially shaped. Zhu De's inscription hanging screen and Tiananmen Square in Qinghai Hall of the Great Hall of the People are carved with crystal salt in green salt. Green salt is a crystalline equiaxed system of halide mineral halite. The crystal is usually cubic, and the aggregate is loose or dense in grain shape and block shape, and the crystal surface has a funnel-shaped step depression.
