  • Flotation separation of copper sulphides from arsenic

    Classified slurry from the grinding circuit is dewatered in a flotation feed thickener from where feeds a three stage copper–lead–zinc sequential flotation circuit. The copper flotation section produces a copper concentrate through two stages of flotation as shown in Fig. 1. Flotation reagents are added through the conditioning tank TKF2.
