feed enters the flotation cell

There appears, however, to be a growing realisation that fines classification at 0.5 mm wedge wire to generate a flotation feed is in many instances not the best choice. The wedge wire permits elongated particles larger than 0.5 mm through and, given screen wear, relatively large particles ~ 1 mm are sent to flotation cells. The flotation recovery of these relatively large particles is often very poor; hence vast
