01.12.2006 · Alkali-leaching and acid-leaching were proposed for the dephosphorization of Changde iron ore, which contains an average of 1.12% for phosphorus content. Sodium hydroxide, sulfuriced, hydrochloric and nitric acids were used for the preparation of leach solutions. The results show that phosphorus occurring as apatite phase could be removed by ...
Dephosphorization - an overview | ScienceDirect …
05.01.2012 · Dephosphorization of iron ore can be achieved through bioleaching. Different methods are needed to remove phosphorus from iron ore depending on whether it is present as a mineral (apatite) or associated with iron minerals ( Edwards et al., 2011 ).
