3. Limonite Flotation process. Limonite has a complex structure consisting of hydrated iron oxides. The flotation method is unique in its ability to selectively separate the desired minerals from the unwanted gangue material using surfactants, thereby improving the overall efficiency of ore processing. Flotation involves the addition of reagents to render …

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 …

The requirement for iron ore is increasing with the rapid development of industry. Therefore, it is necessary to develop a method for the high utilization of high-phosphorus limonite. Traditional processes can't treat low-grade iron ore and are unable to transform the phase of iron minerals, thus they are very inefficient.
