Jul 10, 2020 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, etc., it is difficult to process the limonite ore by.Oct 23, 2018 S + O 2 → SO 2. 4 P + 5 O 2 → 2 P 2 O 5. Roasting is the process of heating iron ore strongly in dry air for drying the ore and expelling humidity, It is used to increase the percentage of iron in the ore and for the oxidation of some impurities such as sulphur and phosphorus Roasting of iron is very important in the ore dressing process but this process pollutes the environment, Ore.
