These generic formulas are frequently all written in the name FeO(OnH2O; this is not even accurate as limonite's often contain a verities of oxide's comparison to hydroxides, and it also has been said that ore are for the process of irons. Limonites are heavy yellowish-brown in color. It is a very commonly substance though which one can be tricked for finding when mined and hematite, bog ore. It is never crystallized into macroscopic crystals, but may have a fibrous or microcrystalline structure, and commonly occurs in concretionary forms or in compact and earthy masses; sometimes mammillary, botryoidal, reniform or stalactitic. The color presents various shades of brown and yellow, and the streak is always brownish, a character which distinguishes it from hematite with a red streak, or from magnetite with a black streak. It is sometimes called brown hematite or brown iron ore.For more clarifications and queries one can also contact the nearest interior decorating department or rather check it online.
