Froth recovery measurement in plant scale flotation

Nov 01, 2003· Savassi et al. (1997) proposed a method to estimate the froth recovery in large flotation cells by collecting samples of pulp just beneath the pulp–froth interface and the concentrate, and mass balancing the flow of attached particles over the froth phase. The advantages of this technique are that it is non-intrusive on the operation of the flotation cell, removes the effect of entrainment, andCited by: 67
