Value Addition of Indian Iron Ore Fines by Column Flotation - Few Case Studies

Vijaya Kumar, T V and Rao, D S and Rao, S Subba and Prabhakar, S and Bhaskar Raju, G (2006) Value Addition of Indian Iron Ore Fines by Column Flotation - Few Case Studies. In: Proceedings of the International Seminar on Mineral Processing Technology and Indo-Korean Workshop on Resource Recycling (MPT-2006), March 8-10, 2006, NML, Chennai.



The Government of India highlighted Processing and utili-zation of iron ore fines as a prerequisite to meet the domestic raw material requirements for the projected 110 million tonnes of domestic steel production by the year 2019-20 in the National Steel Policy announced in Nov-ember 2005. This would require 190 million tonnes of iron ore. The depletion of high grade iron ore and increased generation of fines during mining and handling and demand for high grade iron ore fines for export has necessitated the processing of low to medium grade fines. The R&D efforts undertaken at NML-Madras Centre, India in this direction have been highlighted. Flotation in general and Column Flotation in particular appear to be promising in addressing this problem. This would also mitigate the environmental problem created by the dumping of huge quan-tities of low and medium grade iron ore fines. Three case studies involving iron ore fines of varying silica and alumina content from Goa and Bellary-Hospet regions of India were discussed. The results clearly indicate the feasibility and significance of flotation process in treat-ing the fines to obtain marketable concentrates.
