The operation, when in full production, will produce 5Mt a year of vanadium rich titanomagnetite concentrate grading 0.5%V 2O 5, 8.5%TiO 2 and 57%Fe for export. 90% of the mined sands will be re-deposited on the seafloor in a controlled manner backfilling previous mined areas to enable immediate rehabilitation. The sands will be processed offshore
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.

What is iron ore? Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red.

Received 10 June 1983. accepted 28 May 1985 INTRODUCTION Beach and dune sands rich in volcanic-derived heavy minerals, especially titanomagnetite ("iron sand"), are prominent along the
Magnetic separators remove the titanomagnetite which accounts for about 20% of the sand, but some low grade sand is also trapped. This is removed by gravity in cone concentrators and spiral separators. Sand and water flow over the surface of the cone and the heavier iron minerals sink to the bottom and pass through the slots in the cone.

Titanomagnetite a mineral of the complex oxide class; an intermediate member of the isomorphous series of solid solutions of magnetite (FeFe2O4), ulvospinel (Fe2TiO4), and magnesian ulvospinel (Mg2TiO4). Titanomagnetite is also the name for magnetite with inclusions of the decay products of solid solutions (ulvospinel, ilmenite) and of the substituents

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces

The Onehunga Ironworks was a colonial-era iron smelting and rolling operation at Onehunga, on the Manukau Harbour, (now a suburb of Auckland, New Zealand).. It was at one time claimed to be the largest ironworks in the Southern Hemisphere. The ironworks was located adjacent to the original Onehunga railway station.It operated—but not continuously—from 1883 to around 1895.
A dark mineral called titanomagnetite is found in the sands. It contains iron-rich titanium. Titanomagnetite comes from volcanic rocks in Taupō and Taranaki. The rocks gradually break into grains that end up on the coast as dark-coloured sands. Extracting iron from the sands. From about 1850, people tried to get iron from the sands, to make steel.
