ABSTRACT:
This invention relates to a method for recovering a bulk concentrate of zircon and a bulk concentrate of rutile-ilmenite from dry plant tailings. 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.
