Froth Flotation Reagentsflotation Circuit Design

design of flotation cells and circuits - 911 metallurgist,circuit design and operation. after almost 60 years of application in this country froth flotation is still by far the most important process for concentrating metallic ores as well as a number of nonmetallic ores including fluorspar, phosphate rock, and potash. its.basic flotation circuit design - 911 metallurgist,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 the circuit..
