At the Waikato North Head ironsand mine site resource consents are held for discharges to water and land, as well as water take permits, granted by Waikato Regional Council. Resource consents are applied for before an activity is started and are renewed periodically. To learn about the our manufacturing process go to The Story of Steel >
Port Waikato North Head. At Port Waikato, BHP mines 6 M tpa of ironsand from the North Head, which is concentrated on site to produce 1.2 M tpa of titanomagnetite concentrate. Mining of the deposit began in 1969, and production to the end of 2000 is about 18 Mt of concentrate. The concentrate is slurried 18 km to the steel mill at Glenbrook ...

Ironsand deposits at Taharoa, Waikato North Head, and Raglan (Fig. 1) were selected for our geophysical studies. The field surveys, undertaken between 1974 and 1977, were complemented by laboratory measurements which showed that the density and magnetic susceptibility of ironsand samples are closely related to the concentration (weight percent ...
Dark-coloured sand rich in titanomagnetite is found on beaches on the west coast of the North Island between Whanganui and Auckland. The sand is mined at Taharoa and Waikato North Head.
2 RSC Mining and Mineral Exploration, 93 The Terrace, Wellingto n, New Zealand. The Waikato North Head (WNH) ironsand deposit lies within a ~80- m thick sequence of coastal and river sands near the mouth of the Waikato River.

New Zealand Steel's Waikato North Head mine, situated at the mouth of the Waikato River, supplies approximately 1.2 million tonnes per annum of titanomagnetite concentrate to the Glenbrook steel mill. The mine draws its fresh water supply from the Waikato River, abstracting approximately 38 000 cubic metres per day. During the concentration process of the ironsand, …
The Waikato North Head deposit produces a magnetic mineral concentrate from Quaternary sands that formed in a coastal setting in the North Island of New Zealand. Detailed examination of the magnetic mineral fraction of the different stratigraphic horizons mined at Waikato North Head shows that the youngest units yield concentrates with significant …
