2021.6.24 Modern flotation cell design is based on a cylindrical tank (Figure 2), and these are ommonly known as c Tank Cells. The cylindrical tank design allows for a more even flow pattern than the earlier ‘hog-trough’ style cells and consequentlythese units have better air and solids dispersion throughout the tank. Each tank can have their
