Chalcopyrite is the dominant economic copper mineralization. ... Plant data through the first four months of operation showed that the milling circuit was not making the target tonnage rate (1,585 mtph) and, in fact, was peaking at just over 1,200 mtph by the end of October,
The MA operation strongly enhanced chalcopyrite leaching. The extent of leaching for samples after 10 h, that had undergone 7 h of DM, MM, and WM were 48.9%, 33.5%, and 14.2%, respectively, which were 81.5, 55.8, and 23.7 times higher, respectively, than the leaching efficiency of the nonactivated sample. (3)
In this study, a high-energy planetary mill was used to perform mechanical activation of chalcopyrite in dry-, moist-, and wet-milling modes. Granulometric and microstructural changes of chalcopyrite were characterized, and their effects on Cu dissolution were distinguished.
