recovery and grade prediction of pilot plant flotation
Productive froth flotation technology | FL
Results show that our flotation machines operate on exceptional grade recovery curves, with respect to coarse and fine particle recovery. The remarkable performance of our machines is related to flotationfavourable hydrodynamics, which produce higher active cell volumes, provide longer residence times, and complement froth removal.
