Use of locust bean gum in flotation separation of chalcopyrite and talc
The results of flotation tests performed on mixed minerals indicated that the use of locust bean gum as a depressant can achieve flotation separation of chalcopyrite from talc. A concentrate of 30.1% Cu was achieved at 88.1% recovery from a feed material containing 15.2% Cu.

Behavior of talc and mica in copper ore flotation
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. The copper grade and recovery were affected in the presence of only 7% talc. On the other hand, muscovite influenced the pulp phase via affecting the pulp rheology.
