    Froth Flotation of Iron Ores - sapub

    02.01.2012· In the reverse flotation of iron ores, froth washing was found effective in reducing the loss of FINE iron oxide particles to froth. It was reported that the cost of installing a column flotation circuit is approximately 25% - 40% less than an equivalent flotation circuit of mechanical flotation cells[60]. Industrial application of column cells in iron ore processing has been reported in ...

    Flotation of iron ores can be done in two ways, 'direct' or 'reverse'. In the former, iron oxide is floated. Anionic reagents, such as petroleum sulfonates or fatty acids, are most commonly used. Structurally, these reagents have negatively charged ionic `heads' attached to long-chain organic 'tails'.
