Essar
Project Description - Resource Ore Body

 
Ore body is uniquely able to support a low cost, high quality steelmaking facility

  • Contains large grains of silica and iron

  • Large grains make for easy separation

  • Resulting concentrate is very low in silica

  • Low silica is required for high quality direct reduced iron (DRI)

  • Electric arc furnace (EAF) steelmaking requires high iron, low silica feed
