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 industries.

For example, if you have 5 metric tons, the equivalent weight in short tons would be 5 x 1.1023 = 5.5115 short tons. Conversely, to convert short tons to metric tons, you can multiply the weight in short tons by 0.9072. For instance, if you have 10 short tons, the equivalent weight in metric tons would be 10 x 0.9072 = 9.072 metric tons.
