Mainly uranium but vanadium is also often found in close association with this ore.
It is so because metals cannot be extracted from minerals in a convenient way. E.g.:- Aluminum metal is found in both minerals: clay and bauxite. Aluminum metal is extracted only from bauxite in a convenient way. So, bauxite is an ore of aluminum. On the other hand, it is not extracted from clay so clay remains only as mineral not ore of aluminum.
Rhodium is pretty rare and very expensive. More rare than platinum.
Brazil qualifies as such. It is the third largest producer of iron ore in the world, having extracted 398 million tonnes throughout 2013.
Salt can be extracted from mines or sea water.
Iron
Metal cannot be extracted from Gold, as Gold itself is a metal.
Iron is extracted from haematite.
Aluminium is extracted from alumina.
Bauxite is an ore from which aluminum metal is refined. Aluminum is the most abundant metal in the earth's crust.
Lithium is extracted as the molten metal by a process of electrolysis.
