Iron Ore - AIMR 2011 - Australian Mines Atlas

Australia's iron ore reserves and resources are in both hematite and magnetite ores. Because of the high average grades (% Fe) of hematite ores when compared to the average grades for magnetite ores, it is necessary to report national resources in terms of contained iron.

How is Iron Refined From the Ore? -

What is the process of refining Iron ore? Iron ore refining process uses heat and another substance, so that oxygen molecule can bond to them and separate from iron. Carbon readily bonds with oxygen and so coal or coke (a form or carbon) is used in the iron ore refining process.

Slag - Wikipedia

Ore smelting. In nature, iron, copper, lead, nickel and other metals are found in impure states called ores, often oxidized and mixed in with silicates of other metals. During smelting, when the ore is exposed to high temperatures, these impurities are separated from the molten metal and can be removed.

Iron Ore and Pellets -

What are pellets? Pellets are small balls of iron ore used in the production of steel. They are made with technology that uses the powder that is generated during the ore extraction process, once considered waste.

Iron Ore - Mineral Fact Sheets - Australian Mines Atlas

Although iron ore resources occur in all the Australian States and Territories, almost 90% of identified resources (totalling 54 billion tonnes) occur in Western Australia, including almost 80% in the Hamersley Province, one of the world's major iron ore provinces.

Iron ore - Wikipedia

The Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities.
