BENEFICIATION OF NEW YORK STATE TALC

In accordance with the invention, the preferential flotation of the platy talc from the ore impurities contained in the crushed portion of ore rock is acheived by utilizing a relatively dilute slurry having a solids content of less than about 15 percent by weight. Preferably, the solids content will be 10 or less percent by weight of the slurry.

Behavior of talc and mica in copper ore flotation ...

Talc is a naturally hydrophobic mineral, and therefore it is easily floatable. There have been many studies to overcome this problem, and depress talc with various reagents. In this study the flotation of a copper ore in the presence of talc and muscovite was studied. It was found that talc can affect copper flotation mainly via froth phase.
