    flotation process - an overview | sciencedirect topics

    The linear structure of the flotation cells has a large surface area, which has reject separation and fiber loss. This flotation cell design also contributes to high sludge consistency (less water in the sludge) by ensuring smooth drainage of froth (Aksela, 2008). The elliptical shape of the flotation cells in this technology is optimal for internal pulp circulation for improved ink removal

    the quiet zone flotation cell - oil sands - alberta's

    The advantage of the quiet zone or Q.Z. cell over flotation cells of other types are (a) flotation in a quiet body of water free from turbulence, (b) discharge of tailing, by positive mechanical means instead of by agitation, (c) small power-consumption, and (d) large throughput capacity. . . . the Abasand separation plant not only uses two Q.Z
