conducive environment for production of grinding plant

Mar 01, 2009 In a separate study on a copper ore at plant scale, grinding in a fully autogenous plant mill gave higher fine (−8 μm) chalcopyrite recovery than grinding in a conventional plant ball mill which used mild steel media (Grano et al., 1994) ().For each mill type, samples of the mill products were screened to remove coarse particles, allowing laboratory flotation testing (Grano et al., 1994).
