1. Are you mined (dug up for money) anywhere in the world? Yes
2. Are you an element. I am more than one element.
3. Are you bauxite? No.
4. Are you metallic? The chemists would say I am in part, a metal.but I do not look like a metal any more than silver nitrate looks like silver.
5. Would I call you precious or semi-precious? No. Edit: At least one site says specimens of my general class are sometimes treated as gemstones, but the vast tonnage that is mined annually is not even considered for this possibility.
6. Are you (or have been previously) mined in the U.K. I find no record of such mining.
7. Is one of your elements uranium?I happen to know that a trace amount of uranium is commonly found in me, but it's not part of my chemical formula and I am not mined for it. Edit: in some cases, nontrivial amounts of U isotopes are present.
8. Are you salt. I am not table salt and am more likely treated as a mineral by chemists.
9. Are you found in what is loosely called "mineral sands" as listed in Wikipedia?
https://en.wikipedia.org/wiki/Heavy_mineral_sands_ore_deposits No, I find no mention of me or the product of processing me. Also, my specific gravity is not so great as to make me stand out from the other bits of minerals I hang around with, enough to act like so called mineral sands, which are placer deposits, which type of deposit I am not, at present.
