It is the most common type of iron ore and is found in many parts of the world. Haematite is a reddish-brown or black mineral that is often used as a pigment. It is also used in the manufacture of steel and other iron products.<\/p>\n<p>Magnetite is another type of iron ore that is composed of iron oxide. It is a black mineral that is strongly magnetic. Magnetite is used in the manufacture of magnets and other magnetic products.<\/p>\n<p>Limonite is a type of iron ore that is composed of iron hydroxide. It is a yellow or brown mineral that is often found in swamps and bogs. Limonite is used in the manufacture of iron and steel products.<\/p>\n<p>Siderite is a type of iron ore that is composed of iron carbonate. It is a white or gray mineral that is often found in sedimentary rocks. Siderite is used in the manufacture of iron and steel products.<\/p>\n<p>Haematite is the iron ore which contains 72% of iron.
