· These iron ore deposits, called Kirunatype deposits, account for about 10% of the global production of iron. The researchers have discovered that these iron ore deposits are formed when magma splits into two separate liquids. Author Olivier Namur from the Department of Earth and Environmental Sciences at KU Leuven, Belgium, explains.

However, detection of magnetite, a significant iron oxide in MID (BIFderived magnetite iron deposits) ores, for test samples of BIF drill core proved problematic, and further work is ongoing to optimize the scanning conditions, including laser power and excitation time versus scanning time of the core, to enable detection of magnetite. The addition of other sensors for magnetic susceptibility ...

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, % Fe), hematite (Fe 2 O 3, % Fe), goethite (FeO(OH), % Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO ...

· Sedimentary deposits are represented by the lean siliceous ore of the iron formation, as at Moose Mountain and Temagami, Ontario, and by magnetic black sand found on the north shore of the St. Lawrence; both of these may prove to be important. They can be concentrated magnetically, and this is being done on a large scale with the taconite of Minnesota, the ore carrying only 25% of iron. The ...
