Sep 01, 2020  Iron ore tailing was used as a material for the production of ferric chloride. • Leaching studies were carried out with hydrochloric acid. • Best results were attained with a 10.8 mol L-1 of HCl, a temperature of 80°, and a leaching time of 120 min. • The procedures allowed 94% recovery of iron present in the iron ore tailing. •


Removal of phosphorus from iron ores by chemical leaching

高达10%返现  Dec 01, 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 alkali-leaching, but those occurring in the iron
