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.

The other is to reduce the sulfur content via the iron ore beneficiation process. As a sorting process, flotation plays a fundamental role in this. The objective of the test campaign described below was to reduce the sulfur content in an iron ore concentrate from 1.3 % to less than 0.4 %. The concentrate would thus fulfill the process and environmental requirements with regard to the
