Iron Ore Reverse Flotation

Oxide and Reverse Flotation | Mining | SGS

The bubbles attract and then float the waste minerals, leaving the pay minerals in the underflow. SGS has extensive experience conducting reverse flotation for minerals such as iron ore and fluorite. SGS can determine flotation kinetics, appropriate reagents, and perform computer modeling to design and optimize your flotation circuit.

Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper 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.


This method can be classified in direct flotation when the iron oxides are floated or reverse flotation when the silica’s gangue are floated, Houot (1983 Normally the reverse flotation with amine is used, Iwasaki (1983) and Numela & Iwasaki (1986): The amine is the only cationic collector that is used by industries in reverse iron ore flotation.
