Application of biotechnology in iron ore beneficiation

13.5. Biobeneficiation of iron ore. Most commercially operated iron ore flotation processes, such as the one used by Samarco in Brazil, use the reverse cationic flotation method where the process waters are basic, amine is used as a quartz/silicate collector, and starch is used as an iron depressant (Houot, 1983). As with sulfide ores, the

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.
