iron Fe3+
well it depends. if the solid is dissolved in a liquid ie. salt in water then you could leave the solution in a warm place and after a few days or so the liquid would have evaporated and you would be left with the crystals of the solid ie. salt crystals. Also if the solid is magnetic then you could probably use a magnet ie iron filings with aluminum pins.
anywhere where you could throw away aluminum cans
Intrusive rock normally has visible crystals. Extrusive igneous rock has small crystals. A black extrusive igneous rock with small crystals could be basalt.
Assuming that the crystals have already been formed, as suggested in the question, one could simply filter off the crystals with filter paper, resulting in negligible loss of water. Had the crystals not been formed, the solution could be cooled to create them, and then they could be extracted using the above method, or, alternatively, the water could be evaporated away, and the vapour collected as it does so, allowing for it to be cooled elsewhere, and resulting in little loss of water or crystals.
Ender Crystals could be spawned using Spawn Eggs with ID 200

An Ore.
That depends on several factors such as: the purpose of the wand, how easily the maker could get access to crystals, as well as other things. Most wand will have crystals or jem stones on them but not all do.
