Sintering A Step Between Mining Iron Ore and Steelmaking

Sinter is the primary feed material for making iron and steel in a blast furnace. According to the U.S. Environmental Protection Agency, the sintering process converts fine sized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charging into the blast furnace.
