The resource has been independently measured to contain over 3 million tons of iron oxide in the form of limonite, goethite and hematite, grading 95% on average. Chemically, the iron oxide contains exceptionally low levels of trace metal impurities, enabling its use in market applications that have traditionally been restricted to synthetically ...
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.
Limonite in a ore of iron and is used as a pigment in the manufacture of paints. Besides for a few aesthetic lustrous botryoidal forms of Limonite, as well as the interesting pseudomorphs, Limonite is not of much interest to collectors.
The Orient Mine, active from 1880 through 1932, was the largest producer of iron ore in Colorado, having produced about two million tons of limonite. It is believed that the name Orient came from the Old French word meaning east (rising sun), since the mine is
