    Processing Of Iron Ore Fines By Column Flotation – Part I

    Application of column flotation technology in beneficiation of iron ore fines [5] 2 COLUMN FLOTATION TECHNOLOGY AND APPLICATIONS Column flotation offers mineral processors several opportunities to significantly improve process economics Properly designed and operated columns can deliver high recoveries and concentrate.Laboratory Column flotation studies for reduction of iron ore concentrate remaining in the flotation cell at the end of the test and the tailings collected as froth are analysed for iron silica and alumina 23 Laboratory column flotation tests The automated flotation column with an internal diameter of 74 mm designed and developed by CSIR NML Madras Centre is used in the present study.Jan 02 2012 Although direct anionic flotation was the first flotation route employed in the iron ore industry it was later largely replaced by the efficient reverse cationic flotation route The application of reverse anionic flotation in China in recent years effectively overcomes some flaws of reverse cationic flotation such as high reagent cost and high metal loss in desliming.
