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.

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.

Froth flotation will remain a key unit process for the treatment of iron ores for the decades to come with the overarching challenge best described as being the need to modify and improve existing procedures and processing conditions so as to maintain an acceptable iron grade-recovery response in the face of ores and feedstock that will be ...

Froth flotation is a physico-chemical separation process. Separation is principally based on differences in surface hydrophobicity. However, particle size and density have a significant impact.
