    Galena and chalcopyrite electrodes were used as test minerals. A detailed description of the mineral electrode construction is available in Tadie et al. 28 . A three-electrode electrochemical cell was set up with potentials measured relative to the Ag/AgCl and reported against a platinum standard hydrogen electrode (SHE).

    The two types used in the Mission South Mill are called SAG (semi-autogenous grinding) mills and ball mills. SAG mills use larger pieces of ore to break up the smaller pieces (autogenous — does it by itself). The larger pieces break down as well. To help the process along eight-inch-diameter steel balls are added to the rocks as they tumble

  • A Review on Novel Techniques for Chalcopyrite Ore Processing

       Chalcopyrite ores are usually processed by means of hydrometallurgical or pyrometallurgical processes but due to environmental aspects and the possibility of increased exploitation of mixed and lower grade ores and relatively small isolated deposits there has been a worldwide upsurge of interest in the hydrometallurgical processes of this ore as compared to pyrometallurgy.

    For this study Cryogenic X-Ray Photoelectron Spectroscopy (Cryo-XPS) will be used to determine the lead species present on the chalcopyrite surface after grinding. Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) will be used to determine the distribution of lead by particle size before and after treatment processes.
