Limonite: an iron oxide used as pigment and iron ore. Uses of Limonite. Limonite has been used by people since prehistoric times. Their first use of limonite was probably as a pigment.
Iron is widely distributed in nature (the crust), but since iron is easily combined with other elements to form various iron minerals (compounds), The following is an introduction to these four types of iron ore, magnetite, hematite, limonite and siderite.
Siderite is easily altered to iron oxides. A brown Goethite replacement of Siderite is common. Limonite, an amorphous mineral, is commonly found in rhombohedral crystals, as it frequently pseudomorphs after Siderite.

Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".
Limonite is an ore consisting in a mixture of hydrated iron(III) oxide-hydroxide of varying composition. The generic formula is frequently written as FeO(OH)·nH2O, although this is not entirely accurate as limonite often contains a varying amount of oxide compared to hydroxide.
Like limonite, siderite is a low-grade iron ore that is unstable. The technological processes used in siderite concentrator are gravity separation and strong magnetic separation. Different siderite has different separation methods. Single siderite with coarse grain size is suitable to be treated with single gravity separation, single strong ...

Limonite has been used as a low-quality iron ore for thousands of years. Commercial mining of limonite as a source of iron is no longer done in areas where reasonable deposits of hematite and magnetite are present or readily imported. Limonite deposits are usually too small and too impure for use in modern metallurgy.
Bog iron ore and limonite mudstones are mined as a source of iron, although commercial mining of them has ceased in the United States. Iron caps or gossans of siliceous iron oxide typically form as the result of intensive oxidation of sulfide ore deposits. These gossans were used by prospectors as guides to buried ore.
