Can We Use Hematite In Sponge Iron Making

Why Haematite iron ore is preferred against magnetite iron. As a result, this type of iron ore ore must be concentrated before it can be used to produce steel. In other words magnetite ore requires more treatment than hematite ore wich must undergo only a simple crushing, screening and blending process before being shipped off for production.

2012-5-29  Sponge iron, also called Direct-reduced iron (DRI), is formed, when naturally available Iron Ore which is an oxidised form of Iron (magnetite (Fe 3 O 4) or hematite (Fe 2 O 3)) is reduced to its metallic form. This reduction process occurs below the melting temperature of both metallic iron and its oxidised form. Though this

Sponge Iron - an overview ScienceDirect Topics

DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using gaseous reductants (CO + H ...
