advances in sulphides flotation

Sulphide Flotation - an overview | ScienceDirect Topics

Closed- and open-circuit flotation cleaning is used on gold mines where high-grade concentrates are required for roasting and smelting. Under these conditions, it is difficult to maintain very high gold and sulfide flotation recoveries, while also producing an acceptable grade of concentrate.
