Four main forms of iron ore exist. 1- Of the common iron minerals, magnetite is the richest. It contains iron at 72.4 percent. It is darker than hematite, ranging from deep dark to blackish brown. 2- Hematite, which contains almost 70% iron. It's mostly reddish. A certain amount of hematite is almost black, or even blue. 3- Either limonite or,
Why we need Magnetite’s high-grade iron ore - and heaps of,
13-12-2021· There are two main types of minerals in iron ore deposits sold in the commercial seaborne iron ore market. The first is hematite, which has high in-situ grades of high 50s to mid 60s in iron content, and is the cheapest to develop and operate at large scale, making it the mainstay of the current iron ore market. The second is magnetite.
Why we use hematite over magnetite as iron ore? - Quora
Answer (1 of 5): The structure of hematite is hexagonal and that of magnetite is BCT or inverse spinel. During reduction, the phase change in hematite takes place at a temperature of 500 deg C. This change brings with it an increase in the volume thereby increasing the porosity and increased indi...
