The History of Ironsand | New Zealand Steel

The sand contains mainly ironsand (titanomagnetite) and lime-soda feldspars. Over the centuries, the heavy dark ironsands have been transported by ocean currents along the coast and deposited on beaches, forming dunes of up to 90 metres high.

Ironsand - Wikipedia

Ironsand, also known as iron-sand or iron sand, is a type of sand with heavy concentrations of iron.It is typically dark grey or blackish in colour. It is composed mainly of magnetite, Fe 3 O 4, and also contains small amounts of titanium, silica, manganese, calcium and vanadium.. Ironsand has a tendency to heat up in direct sunlight, causing temperatures high enough to cause minor burns.

Dec 14, 2010 · Titanomagnetite contains admixtures of Al 3+, V 4+, Gr 3+, and Mn 2+. It occurs as octahedral crystals and, more frequently, granular aggregates and black masses. Hardness on Mohs’ scale is 5.0–5.5, and the density is 4,800–5,300 kg/m3. Titanomagnetites are decidedly ferrimagnetic, although ulvospinel is strictly paramagnetic.
