The dominant challenge of current copper beneficiation plants is the low recoverability of oxide copperbearing minerals associated with sulfide type ones. Furthermore, applying commonly used conventional methodologies does not allow the interactional effects of critical parameters in the flotation processes to be investigated, which is mostly overlooked in the literature.
