Refined salt is table salt obtained by purification, processing, refining and other refining processes on the basis of raw salt.

The source of refined salt can be sea salt, well salt, lake salt, or mineral salt.

The technical requirements of the refining process are very high, so the cost of refined salt is higher than that of sea salt. The sodium chloride content of primary salt must be higher than or equal to 99.30%, and the sodium chloride content of secondary salt must be higher than or equal to 98.50%.

It can be seen that refined salt has very few impurities and contains few beneficial minerals, but no heavy metals.

Regardless of sea salt or refined salt, they are all salt, the main component is sodium chloride, and the nutrients are the same.

The content of trace elements in sea salt is very low. If you want to supplement trace elements, you have to eat a lot of salt. You must know that each person only eats 5 to 6 grams of salt per day.

Distribution of salt in China my country's salt production areas are widely distributed, from Northeast China to Hainan and Taiwan, from Xinjiang, Qinghai, Sichuan and Tibet to Inner Mongolia. A wide variety of salts are produced: sea salt, well salt, rock salt, pool salt, etc.

Among them, the salt fields of Liaoning, Shandong, Lianghuai and Changlu are rich in sea salt and have been famous since ancient times.

Well salt is most famous for its artesian wells in Zigong City, Sichuan, which has a history of more than a thousand years. Rock salt is produced in Sichuan, Yunnan, Hubei, Hunan, Xinjiang, Qinghai and other places.

There are many saltwater lakes in Shaanxi, Shanxi, Gansu, Qinghai, Xinjiang, Inner Mongolia, Heilongjiang and other places, which are rich in pool salt. The largest of them is the Chaerhan Salt Pool in the Qaidam Basin.

According to statistics, the salt mined from this salt pond alone is enough for my country's 1.2 billion people to eat for more than 4,000 years.

Others such as Chaka Salt Pond in Qinghai, Jilantai Salt Pond in Gansu, and Jiechi in Shanxi are all famous producing areas of pond salt.
