What is iron ore? Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red.

Magnetite and hematite are common iron-oxides, being found in sedimentary, metamorphic and igneous environments and being associated with a wide variety of deposits styles, including orogenic gold, iron-oxide copper-gold and iron-ore deposits. While the magnetic and mass properties of magnetite and hematite have been comprehensively studied,

What is taconite and why is it used instead of just magnetite or hematite to get iron? Because of their low iron grade, taconite and magnetite require greater processing than hematite in order to form an iron concentrate product of 60-70%. The beneficiation process for taconite requires crushing, screening, grinding, magnetic separation, filtering and finally drying.
