CHAPTER-5 GEOCHEMISTRY OF IRON ORES

The iron ore associated with dolomitic itabirite use to have high LOI (as carbonate) and CaO, very low amount of silica and alumina where as those associated with BHJ/BHQ contain higher amount of silica and alumina. BHJ/BHQ use to contain silica as high as 45-65 wt%. The ore often contains higher amount of …

Banded iron ore such as BHQ is one of the potential resources of iron having a total iron content, i.e., Fe (T) of 35–48 wt%, which is lying unutilized in most of the Indian iron ore mines. The challenge before the policymakers and researchers is to think of a sustainable process technology to utilize these iron ore resources wisely.
