Hematite is the alteration product of many Fe-bearing minerals, especially, magnetite, siderite, and pyrite, and is precipitated in seas and lakes by chemical or organic processes. Its occurrence may be attributed, but not limited, to intense weathering under normal and oxidizing environments.

One of the major advantages hematite ore has over other types like magnetite is its high iron content. That makes the iron extraction process much less costly and time consuming. In addition, hematite ore only goes through one stage of screening and crushing, while magnetite has an additional round of processing. Magnetite

Hematite is the world's most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in deposits in many parts of the world. Hematite is mined in some of the largest mines in the world.

The best known are hematite and pyrite, two iron-based minerals that are often used for ornamental purposes. Hematite is iron oxide that gets its name from the Greek word for blood, since it is red when sliced thinly or powdered. Hematite forms in the rhombohedral crystal system, which is the same crystal structure as sapphire and ruby.

Magnetite has higher iron content than hematite. But hematite ore usually contains large concentrations of hematite; magnetite ore, low concentrations of magnetite. The ore has lower iron content, typically between 25% and 40% Fe. This ore is unsuitable for steel making, and it must be concentrated before it can be used to produce steel.

Which is better magnetite or hematite? While magnetite ore requires more treatment, end products made from magnetite ore are typically of higher quality than those made from hematite ore.That's because magnetite ore has fewer impurities than hematite ore; in this way, the elevated cost of processing magnetite ore can be balanced out.

Soils bearing a string red or orange colour are often iron rich, due to the presence of natural oxides of iron such as pyrite, magnetite or hematite. These oxides, whilst all oxides of the same base metal, can impart wildly different properties to the soil beyond just colour. Such phenomena will be discussed below.

Firstly, till 700 °C, the pyrite onto hematite decomposes in the same extent as pure pyrite, although the shape of heat flow peak is different. The weight loss line has a decreasing tendency till 1000 °C, when fusion is supposed to start, where there is another big decrease in weight which is accompanied by a big endothermic phenomena.
