US5106489A - Zircon-rutile-ilmenite froth flotation ...

A process has been discovered for froth flotation by manipulating the surface charges of dry plant tailings. Conditioning reagents sulfuric acid to lower the pH; corn starch to coat the minerals to be depressed; sodium fluoride to activate the minerals to be floated; and amine to float the activated minerals are used in the flotation process.

Flotation process | Infoplease

Flotation process in mineral treatment and mining process for concentrating the metal-bearing mineral in an ore. Crude ore is ground to a fine powder and mixed with water frothing reagents and collecting reagents. When air is blown through the mixture mineral particles cling to the bubbles which rise to form a froth on the surface.
