Dephosphorization Of Highphosphorus Iron Ore Using

Presumably, the dephosphorization process was mediated due to the chemical attack by the secreted organic acids on the high-phosphorus iron ore, and these organic acids played a vital role in the acidification of the broth, which could be illustrated by the decrease of broth pH, and thus removed phosphate from the solubilized ore.

Removal Of Phosphorus From High Phosphorus Iron Ores

In the process of resource utilization of high phosphorus iron ores, phosphorus should be removed first. Compared to other dephosphorization methods, selective leaching with acid has special advantages such as high dephosphorization ratio, low iron loss and so on. However, a large amount of acidic wastewater containing phosphorus was produced after acid leaching.

Removal Of Phosphorus From Iron Ores By Chemical Leaching

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 ...
