Basic Flotation Circuit Design

2015-8-12  This tank is there to allow the reagents time to become well mixed with the ore and condition it for recovery. 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
