Chrome ore contains too many impurities to be added directly into a steelmaking furnace. Prior to being consumed in steelmaking, chrome ore must be smelted in an electric furnace together with a carbon reductant, which eliminates most of the impurities in the ore and produces a product known as ferrochrome.
iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand export. This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand. This paper deals in brief to use of available methodologies for beneficiation of iron ore in Indian context.
Iron Ore Formation. Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times highgrade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.
