Froth Flotation of Iron Ores sapub

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 centurys practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

An example of this is in the reverse flotation of silica from iron ore, where the silica tailings are floated using a cationic collector at a pH of 8.5 11, leaving behind the iron oxide minerals. Starch acts as a depressant for iron oxide in this process, preventing it from being floated by the cationic collector. 1.5.4
