The upgrading of iron ore is a high-tonnage industry where cost efficiency plays an important role. Reducing costs of the filtration section can be done by the introduction of technology which results in decreased specific energy consumption. The use of the ceramic filter medium can offer this advantage. In addition, the filter medium can withstand chemical regeneration beyond that which a ...

The froth flotation process was patented by E. L.Sulman, H. F. K. Pickard, and John Ballot in 1906, 19 years after the first cyanide process patents of MacArthur and the Forests. It was the result of the intelligent recognition of a remarkable phenomenon which occurred while they were experimenting with the Cattermole process.
Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry.
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.
