Composition Of Iron Ore Low Grade

To tackle the shortage of iron ore, JSW Steel plans to use low-grade iron ore dumps, with 46 per cent iron (Fe) content, at its Bellary steel plant. This would be the first time an Indian steel company would use such low-grade haematite iron ore as raw material. So far, JSW Steel has used iron ore with 52 per cent iron content.

The ore grade, or concentration of an ore mineral or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore. The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore is of too low a grade to be worth mining.
