History of the Iron Ore Trade : The Cleveland Memory Project
This brief history appeared in the 1910 Annual Report of the Lake Carriers' Association. The iron ore trade is, of course, the trade of the Great Lakes, but it was not always so. The premier trade for so many years was grain, then lumber took first place, giving way subsequently to coal. In fact, it was not until 1888 that iron ore became the ...

Introduction: Overview of the global iron ore industry
Abstract. Iron ore is regarded as the second most important commodity behind oil. As an essential input for the production of crude steel, iron ore feeds the world's largest trillion-dollar-a-year metal market and is the backbone of global infrastructure. To meet the growing demand for steel products, world iron ore production has increased ...

Insight into the Origin of Iron Ore Based on Elemental
The origin of iron ore from these BIFs was investigated using a combination of in-situ magnetite and whole-rock chemistry. The studied BIF ore samples have a narrow range of TFe between 30.90 wt.% and 43.20 wt.%, indicating a low-grade ore. The geochemical signatures of magnetite such as low contents of base metals (e.g., …

Iron Ore Type, Formation, Occurrence & Uses
Iron ores are formed due to chemical reactions that combine iron and oxygen in marine and freshwater. The most important minerals in these deposits are iron oxides, magnetite (Fe3O4) and hematite (Fe2O3), goethite, limonite, and siderite. The ores containing large amounts of hematite or magnetite are natural or direct shipping ore.

Iron History
The Iron Age. Within Western cultures, iron began to be used as a productive material around 1200 BC. With early metals being produced from Copper and Bronze during the Bronze Age, the earliest known samples of iron were probably produced by accidentally introducing iron ore into a bronze smelting furnace.
