Can you eat salt from the Great Salt Flats in Utah?

You can, yes. Historically salt was mined from there and used for food. Natives and early settlers would have used the salt for food preservation. These days most of the salt mined on the Flats is mined for Magnesium, the salt by-product is used as road salt for winter driving.

It’s not mined as table salt any longer due to the quality of the salt there. It has to be refined into higher quality, which is very expensive. It’s significantly cheaper to mine salt as rock from underground deposits.

You can buy table salt mined from another nearby site at Redmond Lake. This lake was also formed by the evaporation of Lake Bonneville, just like the Great Salt Flats and Great Salt Lake. So it’s effectively the exact same salt at the Salt Flats.

I have friends who work for Cargill at the salt factory here in Tooele county.

If you live in America and eat salt, it’s likely that salt came from the Great Salt Lake. However, they don’t “mine” the salt flats: they just set up pools of water that evaporate, and extract the salt residue, refining it into something palatable.

“Palatable” is the operative word here. In theory, you could use salt from the flats to spice up your steak, but as it is mixed in with sand and other contaminants, it probably doesn’t taste good.
