  • Recover Ultrafine Chalcopyrite by Flotation

    Dissolved air flotation was the same as conventional laboratory flotation with the following exception. The slurry was conditioned at 50 pct solids in the 500 g Denver DR flotation cell. After conditioning, the slurry was moved to a 1,000 g flotation cell and diluted to 25 pct solids with lime water saturated with dissolved air at 6 atm pressure.
