Hematite, also spelled as haematite, is a common iron oxide with a formula called Fe 2 O 3 and has been widespread in rocks and soils. Hematite forms in the shape of crystals through the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum.Hematite and ilmenite form a complete solid solution at temperatures above 950 °C (1,740 °F).
Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4. It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth.

Different Types of Iron Ore Mineral Processing & MetallurgyImpurities in Iron OresIron Ore FormationOrigin of Iron Ore-BodiesMagnetiteLimoniteSideriteThere are certain impurities that lower the value of iron ores or may even make them valueless. Sulphur in the ore goes partly into the iron and steel and makes them brittle. While it is possible by roasting the ore and by other means to remove the sulphur, the presence of any considerable amount is objectionable. Phosphorus in steel makes it brittle. For steel-making the limit for phosphorus is one hundredth of one per cent for ten per cent of iron in the ore; this is the so-called Bessemer...

Goethite is an iron oxyhydroxide containing ferric iron. It is the main component of rust and bog iron ore. Goethite's hardness ranges from 5.0 to 5.5 on the Mohs Scale, and its specific gravity varies from 3.3 to 4.3. The mineral forms prismatic needle-like crystals ("needle iron ore") but is more typically massive.
Chromite is also common in iron meteorites and form in association with silicates and troilite minerals. Crystal structure. The chemical composition of chromite is Fe 2+ Cr 3+ 2 O 4. Chromite, when presented as an ore, or in massive form, forms as fine granular aggregates.
Different Types of Iron Ore Mineral Processing & Metallurgy
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. Iron formation is believed to be of sedimentary origin

The Extraction of Iron Chemistry LibreTexts
Extracting iron from iron ore using a Blast Furnace. The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air. Coke is cheap and provides both the reducing agent for the reaction and also the heat source.

The ore which contains both iron and copper is chalcopyrite. Its molecular formula is CuFeS2. Its molecular formula shows that it contains both iron as well as copper.
Iron Ores Technische Fakultät
Its importance in older times is unclear to me because it was not distinguished from siderite or bog ore. Goethite forms by "weathering" of more primary iron ores like magnetite or pyrite, involving a change from Fe(II) compounds to the more stable Fe(III) form. It thus is often found in the "gossan" (Eisenhut = iron hat) of iron ore deposits.
