Leaching Dicalcium Silicates from Iron ore Sinter to Remove Phosphorus and Other Contaminants

摘要

Although dicalcium silicates can constitute up to 10 vol/100 of many modern hematite/goethite iron ore sin- ters, traditional mineralogical investigations of such sinters have largely overlooked this phase and focused on the more abundant iron oxides and ferrites. However, dicalcium silicates have a range of properties that make them unique in sinter parageneses.
