Abstract The aim of this study was to improve the dissolution of copper sulﬁde ore composed mainly of chalcopyrite (1.21 wt %) and bornite (0.54 wt %) using a pretreatment before leaching. The effect of the pretreatment on copper sulﬁde dissolution was investigated using different types of leaching.
