I vaguely recall a PBS show, showing how salt is mined from what I think was the Dead Sea.

Basically, pumping the water out on to evaporation plains.

Now that I think about it, the show "Worlds Dirtiest Jobs" showed a honey truck dumping its load on to a concrete
evaporation area, and a frontloader comes along the next day to dump the dried waste into a truck to take to the dump.
