Introduction. Froth stability plays an important role in determining selectivity and recovery in flotation (Farrokhpay, 2011). It should be noted that froth with very high stability is not desirable because in addition to recovering the particles attached to the bubbles, it creates favourable conditions for entrainment (Zheng, Franzidis, and Johnson, 2006).
First off let us discuss why and how sanding occurs, because that does have an impact. Sanding can occur for many reasons, the two main and most common being; 1) poor classification ahead of flotation allowing oversized material to enter the cells, and 2) impeller wear leading to poor mixing in the cell.
