Iron Ore Statistics and Information. Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3 ). Iron ore is the source of primary iron for the world's iron and steel ...

2016-10-5 · Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.

2021-7-27 · Assume a 100-g sample of each ore. Convert that amount to moles by dividing by the ore's respective molecular weight, and then take the ratio of iron in the ore, and the ore itself. Then multiply by the molecular weight of iron to find the weight of iron in that 100 g sample. The mass percent would be massFe / massSample * 100%.
