Figure 5. Comparison of leaching progress assessment through conventional copper solution assays and through CT-based
sulphide dissolution estimation: (a) cumulative leaching progress estimation through each method and (b) trend comparison
between the two leaching progress assessment methods. The vertical error bars correspond to the standard deviations of
the sulphide dissolution estimation for each of the three columns (micro-CT) and of the triplicate measurements of copper
extraction based on solution assays of the PLS, respectively
