Behavior of talc and mica in copper ore flotation

1/8/2018· 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 phaseIn 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 The copper grade andBehavior of talc and mica in copper ore flotation
