  • Removal of phosphorus from iron ores by chemical leaching

    Dec 01, 20060183;32;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 alkali leaching, but those occurring in

    IntroductionIron Ore ExtractionIron Ore ProcessingSintering and PelletizingIron is one of the most important metals in mechanical engineering, as it is present in sufficient quantities on earth. The extraction of iron can therefore be very economical. However, pure iron is not suitable for use as a construction material. It is much too soft in its pure form and has too little strength to meet most mechanical requirements. For this reason, it is necessary to use alloying additives to give the iron its hardness and strength. It has been shown that carbon is an excellent alloying element. Within certain liQuoted Price
