Froth floatation

 · Froth FloatationPresented By:Gulfam Hussain 2. Introduction Floatation is an extractive process where variousminerals can be selectively extracted. Flotation is a selective process and can be used toachieve specific separations from complex ores. For example, in poly-metal ores such as Pb-Zn-Cu, floatation allows separate extraction of Pb, Cuand Zn.
