Silica Concentrate is the impurity in the iron ore which needs to be removed. The current process of detecting silica takes many hours. With the help of some analysis and modelling of data we can give a good approximation of silica concentrate which will reduce a lot of time and effort required for processing iron ore.
For estimation of a Shatter Index, a dried lump iron ore sample (10 kg) of size −40 + 10 mm was dropped 4 times from a height of 2 m onto a cast iron floor (0.5 × 0.5 × 0.03 m). Thereafter, the iron ore was screened and the shatter index expressed as the wt% passing through a …

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.
