Froth Flotation of Iron Ores

Jan 02, 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.

Improving recovery of iron using column flotation of iron

Froth flotation has been established as an efficient method to remove impurities from iron ore in half a century’s practice around the world. Reverse cationic flotation is currently the most widely used flotation route ( Houot, 1983,Araujo et al., 2005,Ma et al., 2011,Ma, 2012,Filippov et al., 2014 ).
