The Ningxiang type oolitic hematite, which is widely distributed in Hubei, Hunan, Sichuan, Guizhou and other regions, is one of the largest reserves of sedimentary iron ore in China. The iron ore reserves of 3.72 billion tons, account for approximately 73.5% of the sedimentary iron ore in China (Lu et al., 1994). The high phosphorus …
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).
High-phosphorus is a typical refractory iron ore that has not been effectively utilized owing to its low Fe grade, fine embedded particle size, and high phosphorus content(Cao, 2023b; Peng et al., 2017; …
Biotechnology could be a cost-effective and environment-friendly way to overcome these problems. Investigations performed by Parks et al. [8] have dealt with the use of fungal strains with high phosphate-solubilizing activity to treat high-phosphorus iron ores. However, the main drawback of this work was that the used strains were not …
