Hydrothermal origin for the 2 billion year old Mount Tom

Giant iron-ore deposits, such as those in the Hamersley Province of northwestern Australia, may contain more than a billion tonnes of almost pure iron oxides and are the world's major source of iron. It is generally accepted that these deposits result from supergene oxidation of host banded iron formation (BIF), accompanied by leaching of silicate and carbonate minerals. New textural evidence

Iron Ore The Canadian Encyclopedia

2006-2-7  Iron ore usually consists of iron oxides and carbonates. Its most important mineral forms are magnetite (Fe 3 O 4,72.4% Fe), hematite (Fe 2 O 3,69.9% Fe) and siderite (FeCO 3,48.29% Fe). In Brazil, some ore that contains practically no other minerals can grade as high as 68% Fe, but the crude ore mined in Canada grades between 30 and 44% Fe.

Mapping iron oxide Cu-Au (IOCG) mineral potential in

2019-10-1  Iron oxide Cu-Au deposits were recognised as a distinct class of ore deposits following the discovery of the Olympic Dam Cu-U-Au deposit in South Australia in 1975 (Hitzman et al., 1992). Since this time numerous IOCG deposits have been discovered globally, and previously known deposits have in some cases been re-classified as IOCG deposits.

Bog iron is much easier to smelt because it contains fewer impurities than iron ore in rock deposits, but the
