Who discovered salt?
The earliest evidence we have for people producing salt comes from northern China, where people seem to have been harvesting salt from a salt lake, Lake Yuncheng, by 6000 BC and maybe earlier.
Some of the earliest evidence of salt processing dates to around 6,000 BC, when people living in the area of present-day Romania boiled spring water to extract salts; a salt-works in China dates to approximately the same period.
