Limonite is commonly deposited in runoff streams resulting from mining operations. It also occurs in lateritic soils, and forms as pseudomorphs over minerals, such as siderite, marcasite, and pyrite.

Jan 23, 2020 · What is limonite made up of? Limonite (/ˈlaɪmənaɪt/) is an iron ore consisting of a mixture of hydrated iron(III) oxidehydroxides in varying composition. The generic formula is frequently written as FeO(OH)·nH2O, although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely.

Limonite, a compound of iron, oxygen, and water [FeO(OH) · nH 2 O + Fe 2 O 3 · nH 2 O], is a yellowbrown to darkbrown or black, seemingly noncrystalline mineral. It is formed by the alteration of other minerals that contain iron. Limonite has a characteristic yellowbrown streak, but its hardness depends on the form in which it occurs.

Used earlier by the iron and steel industry, limonite and other East Texas iron ores have more recently been mined for use in preparing portland cement, as a weighing agent in welldrilling fluids, and in animalfeed supplements. When iron production virtually ceased in 1910, less than 700,000 long tons of ore had been processed.

" Limonite Pseudomorphs after Legrandite Ojuela Mine, Mexico This is a interesting pseudomorph specimen that was collected from the Ojuela Mine in Durango, Mexico. It features the casts of hexagonal legrandite crystals that were encased in limonite.

Mar 04, 2019 · metal mine production in 2018 was estimated at billion, which was 4 percent less than 2017. Lower average metal prices and lower production of many metals contributed to the reduction in value for 2018. The principal contributors to the total value of metal mine production in 2018 were gold, copper, iron ore and zinc.
