Froth Flotation of Iron Ores

 · The flotation routes of iron ore can be classified into five major groups, ionic flotation of iron oxide, ionic flotation of quartz, anionic flotation of iron oxide, anionic flotation of quartz, and combination[2]. Despite the variety of flotation routes developed for iron ores, currently, the reverse ionic flotation route developed by the USBM branch in Minnesota is by far the ...

Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. In the process, hydrophobic particles become bound to the surface of the bubbles. The driving force for this attachment is the ...
