Flotation can be broken down into four different flotation processes: Copper flotation in the unit cell, bulk lead-silver-copper flotation, zinc flotation, and lead-copper separation. The use of a Unit Cell in the ball mill- classifier circuit was indicated as an important step to recover a high percentage of copper.
