·The sea sand vanadium titanomagnetite has the problems of coarse particles difficult agglomeration and poor sintering performance It is difficult for iron and steel enterprises to use it as an ironmaking raw material in large quantities In this work different methods were adopted to optimize the high temperature sintering characteristics of sea sand vanadium
·Residual anomalies were obtained after reducing the magnetic effect of the entire deposit assuming a homogeneous induced magnetisation of A/m equivalent to that of sand with 18% by weight of titanomagnetite The residuals were interpreted in terms of an array of vertical prisms representing the enriched Nukumiti and Paparoa sands
·Direct reduction DR of iron ore with hydrogen is a potential route for near zero CO 2 steelmaking but vertical shaft DR reactors require that iron ore fines must first be pelletized This study reports an investigation of the pelletization and subsequent sintering behaviour of titanomagnetite TTM ironsand which is the main iron ore feedstock for New Zealand s steel
