What Is Iron Ore Sintering? (with pictures)

Apr 02, 2020· 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.
