CHAPTER-9 FROTH FLOTATION AND ITS

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'.
