Limonite ( / ˈlaɪməˌnaɪt /) 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.

From Table 2, the iron elements were mainly found to exist in the form of magnetite, hematite, and limonite in the lowgrade iron ore sample, and hematite and limonite occupied about mass% of the total iron, which should be reduced to magnetite first.. The lignite, obtained from Xinjiang Province of China, was used as a reducing agent. It had a controlled particle size distribution from ...

Ball Mill. Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits. According to the need of customers, ball mill can be either wet or dry designs. Ball mills have been designed in standard sizes of the final products between mm and mm in diameter.

Limonite, one of the major iron minerals, hydrated ferric oxide (FeO(OH)·nH2O). It was originally considered one of a series of such oxides; later it was thought to be the amorphous equivalent of goethite and lepidocrocite, but Xray studies have shown that most socalled limonite is actually

Actually, limonite is a mineraloid and is mainly composed of iron oxides and hydrous iron oxides. It commonly contains hematite (αFe 2 O 3), goethite (αFeOOH), ferrihydrite (Fe 2 O 3 nH 2 O), a small amount of lepidocrocite (γFeOOH) and feroxyhite (δFeOOH). Owing to the unstable chemical composition, high watercontent, easy sliming, etc., it is difficult to process the limonite ore by ...
