Hematite is the most important type of iron ore due to its high iron content, ease of processing, and widespread availability. Hematite is the most abundant iron ore in India and is also found in large deposits around the world. It is a crucial component in the production of steel, as it provides the iron necessary to create the alloy.
The iron minerals that are at present used as ores are hematite, magnetite, limonite, and siderite; also, occasionally ankerite, goethite, and turgite. Hematite is the most important iron ore. The iron content of the pure minerals is as follows: Ankerite is a carbonate of lime, magnesia, manganese, and iron.

Pyrite is a naturally occurring mineral composed of iron and sulfur, with the chemical formula FeS₂. It belongs to the sulfide group of minerals and is known for its metallic luster and brass-yellow color, often mistaken for gold, hence the nickname "fool's gold.". Pyrite is found in a wide variety of geological environments, including igneous, metamorphic, and sedimentary rocks.
