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 (α-FeOOH), ferrihydrite (Fe 2 O 3 nH 2 O), a small amount of lepidocrocite (γ-FeOOH) and feroxyhite (δ-FeOOH). Owing to the unstable chemical composition, high water-content, easy sliming, …

Nickel laterite ore is classified into two principal ore types: saprolite (silicate ore) and limonite (oxide ore). Saprolite-type ore characterized by high magnesia and silica contents is treated by pyrometallurgy process. On the other hand, limonite-type ore is subjected to hydrometallurgy process to produce nickel products. Hydrometallurgy …
