Reagents in iron ores flotation - ScienceDirect

The role of reagents utilised in iron ores flotation is reviewed. Desliming and flotation stages should be performed at pH levels as low as possible to reduce the expenses with caustic soda. Ether amines are by far the mostly utilised class of collector. The degree of neutralisation of the ether amine is an important process parameter.

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'.
