Metallurgist Article about metallurgist by The Free ...

The gases formed (carbon monoxide) reduced the iron oxides. The relatively low temperature of the process and the large quantity of iron slag impeded carburization of the metal and permitted only the production of iron with a low carbon content. The process had low productivity and provided extraction of only about half of the iron in the ore.

Iron Ore Geoscience Australia

2018-12-31  In 2018, Australia's EDR of iron ore increased by 3% from 2017 to 49 604 Mt (Table 3). Similarly, there was a 4% EDR increase of contained iron to 24 122 Mt (Table 4). EDR attributable to magnetite deposits have decreased by 1%, likely due to re-assessment of projects and inactivity in the magnetite industry.
