    Chapter 23: Offshore Mining Industries

    Oct 15, 2017 Iron sand is a general term for sand sized grains (62–2000 μm) of iron rich minerals mainly magnetite (Fe 3 O 4), titanomagnetite (Fe 2 TiO 3) and ilmenite (FeTiO 3). The offshore iron sands in STB, which are mainly derived from Taranaki volcano andesite are the largest known resource of metalliferous ore in New Zealand.The STB project pre feasibility study (PFS) is based on dredging 50Mt of iron sand each year, separating around 10 titano magnetite from the sediment offshore, and returning 90 of the sand to the seabed backfilling mined areas. The sands will be processed offshore aboard a purpose built 345 metre integrated mining vessel (IMV).
