copper metal recovery

    As the next stage in the development of the BioHeap(TM) Process, the
    program will be expanded into the treatment of chalcopyrite-only

    The copper-iron-sulphide mineral, chalcopyrite, is the major source
    of primary copper production from the world's 'great' ore deposits of
    the USA, South America and elsewhere. It is the most difficult ore to
    treat in a bacterial leach and, generally, yields very low copper

    The Titan Resources NL/Pacific Ore Technology (Australia) Ltd
    BioHeap(TM) proprietary bacteria have been shown to be uniquely
    successful in oxidising chalcopyrite in a pure bacterial leach. In
    the leaching of Mt Sholl ore, for example, which contained copper
    levels around 1 per cent, as chalcopyrite, but at considerably finer
    grain size (and hence liberation size) than the nickel, it was
    estimated that only 50 per cent of the chalcopyrite was 'liberated'
    (available to the bacterial action) at the crush size used for the
    nickel. Nevertheless copper recovery of 60 per cent was achieved in
    Heap 1 and a similar recovery is being attained in Heap 2. In other
    words essentially all of the copper accessible to the bacteria was
    successfully leached.

    The implications of the successful application of BioHeap(TM) to
    copper recovery from chalcopyrite ore are huge; much larger in fact
    than for nickel.

    This could have enormous significance for Titan, its from a report some months old, I only just twigged as to what it could mean.
