This salt mine contains a lot of minerals such as iron, which also makes it look particularly pink, so it is called "rose salt".

Commercial rose salt is from such a salt mine, which has not been refined, so it retains those minerals and colors, and also retains larger particles. In short, rose salt is a kind of raw salt with many impurities and pink color.

This salt is more easily touted in Europe and America than in China. The main reason is the appearance of rose salt. The common sea salt or well salt we eat at home is mainly used for seasoning, and the salt ground into fine powder cannot be used as an ornament.

Extended data:

When promoting the "nutrition" and "health care effect" of rose salt, "rich in minerals" is a big selling point. Many sellers claim that, unlike refined salt, rose salt contains "84 kinds of mineral trace elements needed by human body", so its nutrition is also very rich.

A detailed report on the content of rose salt can be found on the Internet, which should be the source of the theory of "84 minerals". In this data report, almost all naturally occurring elements in the periodic table are measured once. At first glance, it's quite spectacular, but even if these data are true, it doesn't explain the problem at all.

At present, there are 1 18 chemical elements found, of which all the elements after 99 are synthetic, and only 98 are left in nature. Among them, hydrogen, oxygen, carbon, nitrogen and inert gases (6 kinds) have never been regarded as "mineral elements", while arsenic, chromium, lead, aluminum, cadmium, mercury and rare earth (17 kinds) have been proved to be unnecessary or even harmful to human body, and naturally have no influence on human body.
