Reduction of Carbon-bearing Pellets of Oolitic Hematite in a Shaft .

Abstract. When carbon-bearing pellets of oolitic hematite are treated in a shaft furnace, some problems are typically encountered: the metallization ratio of the metal pellets is low; the carbon-bearing pellets bond with each other at high temperatures; and the separation of phosphorus from iron is difficult. To solve these.
