Collector For Flotation Of Iron Ore

Objective of this study is to investigate the synergistic effect of dodecylamine kerosene as a collector in the reverse cationic flotation of iron ore slime. The hematite slime used in the investigation contains 56.32 Fe, 5.3 SiO 2, and 5.79 Al 2 O 3. Iron recovery could be enhanced to 64.58 by the mixed dodecylamine-kerosene collector at ...

Studies On The Adsorption Of Flotation Collectors On Iron

Production, the iron ore is upgraded in a number of steps including, among others, flotation. The induced hydrophobicity of the iron ore concentrate caused by adsorption of the flotation collector may affect the pellet strength both in wet and dry state. In order to minimize the influence of the collector on pellet properties it is important to

Chapter9 Froth Flotation And Its Application

The collector is the most important reagent used in the iron ore flotation process. The function of the collector reagent is to promote affinity between mineral particles and air bubbles by formation of a water-repellent coating on the surface of the mineral particle. Most collectors in current use are heteropolar i.e., they contain both a polar

Impurity Removal In The Reverse Flotation Of Iron Ore

Vale is the largest iron ore producer in the world. Since the 1970s, Vale has been using reverse cationic flotation to remove siliceous impurities from its iron ores. Whilst this flotation process has operated effectively for many years, it suffers from the problems of high reagent costs and high metal loss.
