Pictures?
Useless exercise in memorizing photos, many of which aren’t common or even naturally occurring. Chemical formulas would have been more useful. I wasted my money. Can I get it back? Also, bauxite isn’t mineral but a combination of minerals. Beryllium, antimony, lithium, tungsten, vanadium, and barium only occur in combination with other elements in nature. Titanium can only be found in nature as an oxide. Mica isn’t a mineral but a group of minerals. Perlite isn’t a mineral but amorphous volcanic glass. Potash isn’t a mineral, neither is rare earth elements, or silica, or sodium carbonate. This isn’t a collection of minerals so much as a collection of elements. The lithium photo is of ingots. I can see many of the pictures come from Wikipedia.

Look at a mineral get an answer then repeat and get a 30 second advertisement. And so it goes on.
