Mining | Flotation of Iron Ore | Nouryon

The main objective of iron ore flotation is to upgrade the concentrate by removing silicates and/or phosphorus-containing minerals. The use of silica flotation has increased in recent decades. The trend will continue as more complex ores have to be mined and higher-grade iron ore concentrates with fewer impurities are requested by the steel ...
