Iron Ore Reverse Flotation Introduction - Xinhai

2017-12-19  In iron ore direct flotation process, a sort of direct flotation reagent is added and then works under specific conditions. The floating material is mainly iron concentrate. On the contrary, iron ore reverse flotation uses reverse flotation regents to work under given conditions, and its floating material is mainly gangue mineral.

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.In 2010, CSIRO investigated the use of a reverse anionic flotation process for Vale ...

SIDERITE ORE PHYSICAL SEPARATION AND REVERSE

2013-6-11  iron ore slimes [5]. When the test sample contains relatively lesser gangue, it is easier to float it and hence reverse flotation can be employed rather than direct flotation where in major proportion of the material, otherwise, would have to be floated. As such, the reverse flotation is the usual process for the beneficiation of iron ore slimes.
