DEVELOPMENT OF INDIGENOUS COLUMN FLOTATION

2011-9-26  Abstract: NMLMadras Centre has designed and developed indigenous automated flotation columns as part of itslong termRDprogramon the utilization of low-grade ores of India. Both laboratory size and semi-commercialflotation columns were extensively field tested indifferent mineral processing plants owned by Hindustan CopperLimited, Hindustan Zinc Limited, Kudremukh Iron Ore Company Limited, Sociedade De Fomento IndustrialLimited, Bharat Gold Mines Limited, Gujarat Mineral Development Corporation Limited and Indian Rare EarthsLimited for the beneficiation of copper, lead and zinc, iron, gold, fluorspar and sillimanite. State-of-the-artequipment was incorporated in both laboratory and semi-commercial flotation columns. Advantages of columnflotation technology over conventional flotation machines and salient features of the NMLflotation column werediscussed inthe present paper. Flotation test results obtained both byflotation column and conventional cells werecompared. The paper also highlights the potential of column flotation technology
