Salt inhibits most organic 'growing'.

Salt being Sodium Chloride (NaCl), are you asking if salt has impurities in
it? (There's also the world of potassium salts IIRC.)

Likely you know the usual difference between table salt and sea salt is that
table salt commonly has iodine added.

Humans apparently need a bit of iodine on a regular basis.

To my thinking, mined salt could be contaminated by other elements or
compounds suspended/mixed in it or coated on it.

Same with sea salt one would think.

But I'm no expert on salt, I'm a musician and audio engineer. Those things
I know a fair amount about.

***Here's a trick***

Dissolve some of your salt, say, 6 tbs in 1/2 c purified water; stir well,
let it sit for a while and see if you observe anything floating (film or
particles) on the surface or the bottom.

This process (flotation/settling) is a way to remove impurities from
material, used in mining for one.

You could boil it for a while to amplify the process.

Also filter it through bacterial air-mask material, see if any residual
stuff.

Could be very small, a good magnifying glass or microscope comes in handy.
