Most of those things are not micronutrients humans need.

Farmed salt of today is contaminated with anything that is in the sea, including microplastics. If you don't want "chemicals" and want "natural" avoid farmed salt.

That's a really good point. I'm definitely in favor of processing, just picky about the end results. Removing microplastics sounds like a great process. Improvements like this to salt farming could have huge benefits.

> Removing microplastics

How do you propose to remove grains of plastic the size of salt crystals from the salt? And once done is it affordable or commercially viable?

Validation of density separation for the rapid recovery of microplastics from sediment ?

as the discussion on the article mentions particles > 1mm are still pretty large.
