The leaching performances of the feed, agglomerates, and coarse-grained ore were observed by estimating their bulk density, slumping, permeation rate, and leaching rate (Dhawan et al., 2013). The permeation rate was expressed in terms of the outflow velocity of the liquid after the samples were saturated, which was calculated by Eq.
