Evaporative ponds account for millions of tonnes per annum ... and that's just from two sites:

Out of many worries about this world and its future, running out of salt is really at the bottom of the list.
You can always extract it form the sea by mere evaporation like our ancestors did. Plus salt deposits in the ground all over the world are massive, we had salty seas for billions of years.
Not sure why you're getting downvoted. People shouldn't get punished for asking questions.
When that one mine runs out of salt? It will be closed. We as a humanity will not run out of salt, some places have the opposite problem: https://en.wikipedia.org/wiki/Monte_Kali
"According to the Werra Potash Mining Museum in Heringen, Monte Kali has been in operation since 1976; as of August 2016, it covered 98 hectares (240 acres) and contained approximately 201 million tonnes of salt, with another 900 tonnes being added every hour and 7.2 million tonnes a year."
