An overview of reverse flotation process for coal ...

Flotation is one of the most effective technologies for the upgradation of coal fines of particle size below mm because of the inherent hydrophobic nature of to this, reverse flotation of coal in which coal particles are depressed and gangue particles floated, was developed as an alternative process to minimise the sulphur content in the coal.

Iron Ore Reverse Flotation Introduction Xinhai

In iron ore direct flotation process, a sort of direct flotation reagent is added and then works under specific conditions. The floating material is mainly iron concentrate. On the contrary, iron ore reverse flotation uses reverse flotation regents to work under given conditions, and its floating material is mainly gangue mineral.
