tunnel kiln iron ore reduction

Reduction of iron ore briquettes into DRI in the tunnel ...

In the first and second generation tunnel kilns, iron ore coal layers were separate. In the new design, iron ore lumps / briquettes and coal fines are mixed together and hence the reduction is faster. The loading unloading systems are also simple. The third generation tunnel kilns are available in capacities from 30,000-70,000 tons per year ...

Direct reduced iron - Wikipedia

Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal.Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting ...
