    The dominant challenge of currentcopperbeneficiation plants is the low recoverability of oxidecopper-bearing minerals associated with sulfide type ones. Furthermore, applying commonly used conventional methodologies does not allow the interactional effects of critical parameters in theflotationprocesses to be investigated, which is mostly overlooked in the literature.
