Froth Flotation of Iron Ores - sapub

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].
