Introduction. Australia's iron ore industry is undergoing a major transformation. Reserves of traditional high-grade ores are becoming depleted while the replacement ore types are lower in grade and sometimes require beneficiation to remove or minimise contaminants such as alumina, silica and phosphorus (Dukino et al., 2000).

Despite the abundant reserves of iron ore resources in China, the overall iron ore is characterized by the behavior of low grade, fine grain size, and high …

The iron ore industries of India are expected to bring new technologies to cater to the need of the tremendous increase in demand for quality ores for steel making. With the high-grade ores depleting very fast, the focus is on the beneficiation of low-grade resources. However, most of these ores do not respond well to the conventional …

Meanwhile, the average annual growth rate of imported iron ore was 20%. The growth rate of imports was obviously higher than that of self-produced ore. Since 2000, China's iron ore imports, except a slight decrease in 2010, 2012 and 2015, increased substantially, the annual import grew twice over 35%.

Iron ore is essential in steel making; however, high-grade ores have diminished, making low-grade ores inevitable. These low-grade iron ores need further beneficiation to upgrade the iron content. Currently, traditional physical and chemical methods are utilized and are not environmentally friendly. Bio-beneficiation techniques …
