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 ...
