Offshore iron sand extraction in New Zealand:

2017-10-15  (2) The extraction and processing of iron sand involves rapid mixing of this sand with fully oxygenated seawater. This mixing may mobilise trace metals via oxidation of metal sulfides and metal-adsorbing pyrite and iron monosulfides ( Morse, 1995 , Simpson et al., 1998 ).

Offshore iron sand extraction in New Zealand:

We conducted dilute-acid extractions and standard elutriate tests to investigate the potential of this exploitation to (1) create a new seafloor with elevated trace metal content, (2) mobilise trace metals during iron sand extraction and, (3) enrich the returning process seawater, which feeds iron sand through mills, with trace metals.

How iron is made - material, manufacture, making,

The process of extracting iron from ore produces great quantities of poisonous and corrosive gases. In practice, these gases are scrubbed and recycled. Inevitably, however, some small amounts of toxic gases escape to the atmosphere. A byproduct of iron purification is slag, which is produced in huge amounts.
