The slurry flow then enters the feed end of the flotation cells. The slurry at this point is called the HEADS of the circuit. The mineral is then separated and flows over the overflow into a trough called a flotation cell LAUNDERER. The OVERFLOW is now called the flotation CONCENTRATE of the circuit.

The selected feeder must not only control flow but work well with your bin. Reliable flow is highly dependent on the flow pattern that develops in your bin. The two flow problems that develop are funnel flow and mass flow. A bin flowing in funnel flow discharges some material while most remain stagnant, typically built upon the bin walls.
