Froth Flotation of Iron Ores

02/01/2012  With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century’s practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

Flotation Process - an overview ScienceDirect Topics

The flotation process is characterized by the following: ... First, the collector is added to the iron ore slurry to selectively coat the iron oxide particles, making the surface hydrophobic. The slurry then goes to a flotation cell, where air bubbles are generated using an impeller and aerator (Figure 1.2.4). At this step, the frother (for example, fuel oil) is added to the ore slurry to form ...

01/02/2005  The flotation performance of certain iron ore types is enhanced with the use of ether di-amines in combination with ether mono-amines. Amine is partially replaced by some kind of fuel oil in some concentrators. The emulsification of the fuel oil plays a relevant role in the process. The price of fuel oil is lower than that of amine and no significant environmental impact was detected. Amine ...

Pneumatic flotation Application of Hybrid Flotation in the ...

08/07/2017  Iron production generally follows a fixed process chain. Ore extraction in the mine is followed by the downstream processes of beneficiation, pelletizing or sintering, followed by the blast furnace or direct reduction process (Fig. 1). In the beneficiation system, the flotation is a sorting process that assures achievement of the mineral contents necessary for the downstream processes.

Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process.
