Based on my previous question over here, [which starts up and talks about a desert which is full of ore sand instead of normal sand.](https://worldbuilding.stackexchange.com/questions/10757/the-desert-of-ore-how-is-it-different-from-a-desert-of-sand) 

What would people need to be able to simply live in it, since there would be that much ore dust all over the place?

The next and probably last question for now will be over here, which will be, how would the people living there be able to harvest, sort and smelt the ore sand.
