There is compulsion to export iron ore fines at present in the overall interest financial viability of iron mining. Fines are co-produced with the lumps in the ratio of Lumps to Fines in the ratio of 30:70. On an average, for production of 1 tonne of lumps, about 2.5 tonnes of fines are produced. In Goa and Karnataka regions, the ratio is 20:80.
