Magnetite sand: Some beach and river sands contain high concentrations of magnetite. Magnetite-rich "black sands" are commonly encountered by people panning for gold. Although magnetite sands and other heavy mineral accumulations are common, they are infrequently developed as mineral deposits because their size or grade is inadequate.

Some particles, such as magnetite, are prevalent in black sand and, unlike gold, are attracted by a magnet. Magnetic components are not extremely valuable, except for platinum. Now, just picking your old horseshoe magnet won't do. You need a very strong magnet, such as those specifically geared towards gold miners. These are strong enough to ...

Magnetite is the primary source material for this. Ground magnetite is partially reduced, relieving it of some of its oxygen, leaving a catalyst bearing a magnetite core with an outer shell of ferrous oxide (FeO, würstite). The advantage of this catalyst comes in its porosity, and thus it is a highly active, high surface area material.
