Quantifying contributions to froth stability in porphyry copper plants

M Zanin, E Wightman, SR Grano… - International Journal of …, 2009 - Elsevier
A method to describe froth stability in industrial flotation cells, and its link with froth recovery,
is discussed in this paper. The direct measurement of froth stability in industrial flotation cells
is still controversial, and different techniques have been developed. In this paper, the froth
half-life time and bubble size on the top of the froth are discussed as indicators for froth
stability. Experiences at two flotation concentrators treating porphyry copper ore are
compared. The relative contributions to froth stability from frother in solution and solids …
