How is Iron Refined from Ore? (with pictures)

To purify and strengthen iron, materials like coke are mixed in with it to remove oxygen. To coax the oxygen atoms away from the ore requires heat and an alternate atomic partner for the oxygen to bond to. Carbon fills this role nicely, and is readily available in the form of everyday charcoal, or coke, a form of carbon made from coal.

Iron Oxide-Copper-Gold (IOCG) Deposits of Australia ...

Typically, IOCG deposits are prospected for their concentrations of copper. In the deepest parts of the deposit, the main copper mineral disseminated within the brecciated rock and locally concentrated in veins is chalcopyrite, a copper iron sulphide. Higher up in the deposit the mineral bornite, also a copper iron sulphide mineral, is more common.

Gold in iron oxide copper–gold deposits - ScienceDirect

Ubiquitous presence of magnetite and apatite in gold-sulfide association, alteration patterns and shear controlled mineralization suggest it to be IOCG (Iron-oxide copper gold) type deposits. The detailed mineral chemistry of magnetite and apatite are generated and interpreted in terms of their genetic significance, hydrothermal and magmatic origin vis-à-vis their affiliation with IOCG deposition.

Iron oxide copper-gold (IOCG) deposits were only recognised as a class of mineral deposits following the discovery of the Olympic Dam deposit in South Australia in 1975. These deposits, characterised by the presence of abundant magnetite and/or hematite, often have gold associated with the copper and are hosted by intensely altered rocks, which contributes to the diverse mineralogy.
