  • What Is Iron Ore Sintering? (with pictures)

    27/10/20190183;32;Iron ore sintering is a type of powder metallurgy used to pre treat iron before using it in manufacturing applications. Sintering involves heating iron powder to partially, but not completely, melt the iron particles. The exact process used and additional elements involved vary, with some methods using gas or electricity in addition to heat.

    The main effect on iron ore mineralization performance in the sintering process is the grain size of raw material and chemical composition. The results show that 0.5mm particles can mineralize, but +0.5mm particles remain a nucleus in sinter. This paper analyses the effect of the chemical composition on mineralization characteristics of liquid production.
