Flotation Characteristics of Amphibole-Type Oxidized Iron Ore via
Abstract. To explore the flotation feasibility and flotation law of iron minerals from amphibole-type iron oxide ore with full-size minerals, a systematic study Introduction. Froth flotation is the most important process to produce superconcentrates from low-grade oxidized iron ores. The efficiency of the process strongly depends on bubble size and froth stability, requiring the use of frothers. The flotation dynamics involves the collision and adhesion between bubbles and mineral Effects of surfactants combination on iron ore flotation

Collecting Agent–Mineral Interactions in the Reverse Flotation
Froth flotation has been widely used in upgrading iron ores. Iron ore flotation can be performed in two technical routes: direct flotation of iron oxides and reverse flotation of gangue minerals with depression of iron oxides. Nowadays, reverse flotation is the most commonly used route in iron ore flotation. This review is focused As quartz is the main gangue mineral in iron ores, this section focuses on the interactions between collectors and quartz in aqueous solution. The interactions between collectors and non-quartz gangues will be discussed in Section 3. 2.1. Anionic Collectors Fatty acids are widely used as a collector in the reverse anionic flotation of iron ores.Flotation of Iron Ore: A Brief Review MDPI
