Technical Resource Document: Extraction and Beneficiation ...
Approximately 97 percent of all usable ore for the production of iron and steel is now sold in the form of agglomerated pellets. The remaining 3 percent of higher grade usable ore (wash ores) is sold in original form directly to blast furnace operations or in the form of other agglomerated products.
Froth Flotation of Iron Ores
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.
NPI Emission Estimation Technique Manual for Mining

Is column flotation still relevant? - AusIMM Bulletin
Flotation column capacity in iron ore has also been significant, representing nine per cent of the installed column total. The majority of this is in Brazil (67 per cent of installed iron ore column flotation capacity), with the other countries utilising columns for iron ore flotation including China, Peru, USA, Russia, India, Mexico, South Africa, Venezuela and Chile.
Oxide and Reverse Flotation | Mining | SGS
Aeration is added through spargers at the bottom of the flotation cell. 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.
1 Froth Flotation – Fundamental Principles
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. The particles with attached air …
Froth flotation - Wikipedia
Principle of operation. Before froth flotation can work, the ore to be treated is reduced to fine particles by crushing and grinding (a process known as comminution) so that the various minerals exist as physically separate grains. This process is known as liberation.
