REMOVAL OF PHOSPHORUS THROUGH ROASTING OF
Forssberg and Adolfson (1981). In this study P was also present mainly as apatite and its leaching was carried out with 2M HCl and 2 – 6 M HNO. 3 . at temperatures between 10 and 60°C and duration of up to 30 hours. Leaching after roasting to 300°C has been tested with Australian iron ores rich in phosphorus present as apatite by Edwards,Concentrating of Iron, Slag and Apatite Phases from High,,removing impurities from alloy melt,30,31) the super gravity field was applied to the iron-slag separation process at low temperature in this study. In this paper, the experiments on concentrating of iron, slag and apatite phases from high phosphorous iron ore gaseous reduction product at 1 473Characterization studies on Agbaja iron ore: a high,,Iron ores with phosphorus content lower than 0.07% P are commercially desired as they are suitable for use in iron production. As a consequence, a lot of research efforts have been focused on phosphorus removal from high-phosphorus iron ore [20, 24, 32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48] in a bid to reduce the P content to acceptable levels.
