iron ore concentrates using flotation conlumns

CPT Inc has developed a flotation process for the production of Direct Reduction DR as well as Blast Furnace BF grade concentrates utilising column flotation technology This process has been adopted by several major iron ore producers and current aggregate production is approximately 50 MTPY of DR grade concentrates

many ironore producers worldwide are considering columns as a viable alternative to conventional flotation machines for the reduction of silica in fine pellet feed The ability to operate with wash water and deep froth beds results in improved iron recoveries particularly when producing direct reduction grade concentrate

The reverse flotation process of iron ore is used in iron ore with complex iron mineral composition and high iron grade It is mostly used to process coarse concentrates of gravity separation and magnetic separation to obtain highgrade iron ore There are two types of reverse flotation technology for iron ore one is anionic collector reverse

Oct 01 1992 · In reverse flotation of silica from ironore concentrates washing has been effective in reducing fine iron losses to the reject stream Recent cost comparisons5 have shown that the cost of installing a column flotation circuit can be 25 40 less than an equivalent conventional flotation

The use of these new reagents may bring an innovative concept of iron ore and tailings reverse cationic flotation without the need of using starch as iron oxides depressant Herein this higher selectivity allowed a peculiar separation of iron and siliceous concentrates in a single rougher operation without the employment of starch as depressant

Flotation columns Getting the most from fine ores Flotation columns Getting the most from fine ores The first flotation machine design to use the column concept was developed by Town and Flynn in 1919 – a column was used with an injection of air in the bottom by a porous plate
