Abstract

Abstract

In order to achieve high gasification dephosphorization of high-phosphorus iron ore after sintering,promote the development and utilization of high-phosphorus iron ore,the influence of material com-position on the gasification dephosphorization rate had been investigated via microwave heating. When u-sing bituminous coal,5% C/O,0.75% SiO₂ addition,1.5% CaCl₂ addition and 1.4 of alkalinity, high-phosphorus iron ore fines could be achieved 20.36% of gasification dephosphorization in the microwave field. X-ray diffraction(XRD) results on the calcined product found out that excessive addition of CaCl₂ would produce Ca₅(PO₄)₃Cl, and not favorable for gasification dephosphorization.
