    Case of Study for a PbS flotation circuit. I have worked on a PbS lead ore (2.3 Pb feed) and I got a 50 grade and 60 recovery by applying a flotation circuit (see figure below). Then I wanted to increase both the grade and recovery. After several analyses I concluded that it is the liberation size that would have more effect.
