Froth Flotation of Iron Ores - article.sapub

2012-1-2  A variety of flotation routes have been developed to remove silica from iron minerals. The flotation routes of iron ore can be classified into five major groups, i.e. cationic flotation of iron oxide, cationic flotation of quartz, anionic flotation of iron oxide, anionic flotation of quartz, and combination [2].

Brief Introduction on Iron Ore Mines Mining Process -

2015-12-15  Flotation is one of the common methods for separating the weakly magnetic iron ore mine from fine to ultra-fine particles, including positive flotation and reverse flotation. The former is suitable for quartzite hematite without easily floating gangue, while the latter is suitable for the weakly magnetic iron ore mine easily floating gangue ore.
