  • A Review on Novel Techniques for Chalcopyrite Ore

    2012 1 1ensp;0183;ensp;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.

  • Cobalt Mining Legacy

    Acidic Drainage At many mines in Canada, including both operating mines and closed or abandoned mines, acidic drainage is a big concern, and a lot of research has been done to figure out how to prevent or control acidic drainage, to protect the environment. Acidic drainage happens when sulphide minerals are exposed to both water and air. In sulphide minerals, metals are bonded to sulphur.
