  • reverse flotation of iron ore

    hence reverse flotation can be employed rather than direct flotation wherein major proportion of the material,otherwise, would have to be floated. As such,the reverse flotation is the usual process for the beneficiation of iron ore slimes. Amines are the only cationic collectors used by industries in reverse flotation of iron ores. Chat Now

    This study investigates the removal of silica and alumina as impurities from hematite based low-grade iron ore containing 34.18 mass% iron, 31.10 mass% of silica and 7.65 mass% alumina. Wet high-intensity magnetic separation (WHIMS) and reverse flotation (RF) were investigated. In WHIMS process, 93.08% of iron was recovered with a grade of 53.22 mass% at an optimum magnetic density of 10,000 ...

    Reverse flotation to remove quartz has been proved to be a very effective technique in the industry. Reverse cationic flotation of quartz uses mainly fatty amines and their derivatives as a collector, e.g. mono-amine, di-amine, and ether amine or a mixture of di-amine and mono-amine (Araujo et al., 2005).
