• collector for magnetite ore flotation

    AkzoNobel Surface Chemistry Flotation Collectors. Flotation systems for removing silica from magnetite ores have to be designed differently compared to the systems for treatment of hematite ore. There are several reasons for this but in all magnetite flotation, the collector must have the capability to float mixed magnetite-silica grains.
