Bauxite is the name for a mixture of similar minerals that contain hydrated aluminum oxides. We require metals for making machines, sands and gravels for making roads and buildings, sand for making computer chips, limestone and gypsum for making concrete, clays for making ceramics, gold, silver, copper and aluminum for making electric circuits, and diamonds and corundum sapphire, ruby, emerald for abrasives and jewelry. The table below lists average crustal abundances and concentration factors for some of the important materials that are commonly sought. Thus, deposits containing the mineral gibbsite [Al OH 3 ], are usually sought. If your mineral is softer than 7.

Reference books that can help you to identify minerals, rocks, rocks, fossils, and meteorites are available for purchase in our gift shop. By dividing this economical concentration by the average crustal abundance for that substance, we can determine a value called the concentration factor. Most minerals are very rare and their identification often requires a mineralogist that is trained in the use of microscopic and other analytical techniques.
If your mineral bubbles and fizzes, you probably have a sample of calcite. Note that we will not likely ever run out of a useful substance, since we can always find deposits of any substance that have lower concentrations than are currently economical.
