Froth Flotation of Iron Ores
The two anionic flotation routes developed by Hanna Mining and Cyanamid, i.e. direct anionic flotation and reverse anionic flotation routes, are also being used in the iron ore industry. The history of iron ore flotation started with direct flotation of iron oxides using anionic collectors such as petroleum sulphonate, fatty acids and hydroxamates.

The main objective of iron ore flotation is to upgrade the concentrate by removing silicates and/or phosphorus-containing minerals. The use of silica flotation has increased in recent decades.
Flotation | ore dressing | Britannica
The flotation process was developed on a commercial scale early in the 20th century to remove very fine mineral particles that formerly had gone to waste in gravity concentration plants. Flotation has now become the most widely used process for extracting many minerals from their ores. Schematic diagram of a flotation separation cell.
Froth Flotation Process - Mineral Processing & Metallurgy
The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents:
Flotation collectors optimized performance
Flotation of iron ore The main objective of iron ore flotation is to upgrade the concentrate by removing silicates and/or phosphorus-containing minerals. The use of silica flotation has increased in recent decades. The trend will continue as more complex ores have to be mined and higher-grade iron ore concentrates with fewer

Flotation process is also commonly seen in nowadays iron ore beneficiation. It has become a very important way to recover weak magnetic ore. It is also used to treat iron ore fine to reduce the content of silica and impurities. Flotation beneficiation separates ore by different physical and stone properties of different materials.

Froth flotation - Wikipedia
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, stone recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the recovery and upgrading of …
Beneficiation of Iron Ore - Mineral Processing & Metallurgy
Magnetic separation on average ores with 25 to 30% iron results in about 1/3 of the total tonnage ending up in final concentrate. CONDITIONING AND FLOTATION. The iron concentrate as it comes off the magnetic finishers is well flocculated due to magnetic action and usually contains 50-55% solids. This is ideal dilution for conditioning ahead of flotation.
1 Froth Flotation – Fundamental Principles
Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry.
Recovery of Iron Ore Tailings byColumn Flotation
Introduction The concentration of iron ore by flotation is a technique consolidated worldwide for mineral particles ranging from 10 to 250 μm. In Brazil, all the main pellet-feed producers use re- verse flotation, being the tailing made up mostly of quartz and a concentrate constituted of iron oxides and iron hy- …
