Iron sand is a mineral that can be found near beaches, swamps and river mouths; deposits normally extend from the surface to a depth of 15 meters. The process of extraction of iron sand involves passing the material through a machine equipped with a magnet that separates the iron sand from nonmetallic components such as sand, earth and rocks.
Many such deposits around the globe have been studied as potential sources of iron ore, but few are of commercial value. The seabed resource. While the land based deposits are significant (see appendix), the amount of iron sand in the seabed is far larger in scale. This has been described as New Zealand's biggest mineral resource.
