From ironsand to steel – Iron and steel

Ironsands are taken from the beach at Waikato North Head and reduced to an iron-rich concentrate. This is piped to the Glenbrook steel mill. There it is blended with coal from nearby Huntly and reduced to molten pig iron by smelting. Recycled steel scrap is added to the molten iron, and liquid steel is produced.

NZ ironsand is a commercial iron ore which occurs as sand deposits along a 400 km length of the west coast of NZ's North island [16]. It is easily beneficiated using low-cost magnetic separation, to produce a concentrate that predominantly comprises particles of titanomagnetite (TTM). The key difference between NZ ironsand and conventional ...

Pelletization and Sintering of New Zealand Titanomagnetite Ironsand

Direct reduction (DR) of iron ore with hydrogen is a promising alternative ironmaking process with near-zero CO2 emissions. This approach is applicable for the reduction of New Zealand (NZ) titanomagnetite (TTM) ironsand, which offers the potential for establishing a clean steelmaking industry in NZ. However, iron ore fines must first be …

Making iron. In the earth's crust there are minerals known as ores. These contain metals such as iron and copper. Many countries have plenty of iron ore, usually dug from the ground. Lumps of ore are heated in blast furnaces fired by coal or coke and blasts of air. After a chemical reaction, molten iron settles to the bottom and is poured off.
