Flotation is an important process used in the concentration of iron ores. one of the challenges for process engineers is the low metallurgical recovery associated mainly with the fines fraction. in this work the use of synthetic flocculants in iron ore reverse cationic flotation was investigated. the flocculants utilised were polyacrylamides of high molecular weight...
Flotation process is also commonly seen in nowadays iron ore beneficiation. it has become a very important way to recover weak magnetic ore. it is also used to treat iron ore fine to reduce the content of silica and impurities. flotation beneficiation separates ore by different physical and chemical properties of different materials.
Flotation response of iron ore depends on its impurities. • silica rich ores float better compared to alumina rich ores. • clay and gibbsite coat on hematite and hinder flotation. • sem studies support less coating of quartz due to coarser size. • silica in the form of jasper present in bhj ore is less floatable.
For brazilian iron ore producers reverse cationic flotation is preferred to obtain high quality concentrates from silicate ores. the sio2 silica particles are rendered hydrophobic by amine cationic collector in alkaline conditions while iron is depressed by the addition of starch.
