Characterisation of phosphorus and other impurities in ...

2019-11-1  1. 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).The phosphorus content of Australian iron ores is a particularly ...
