Conclusions

  1. 1.

    Mechanical activation of pyrrhotite concentrate leads to partial amorphization of crystal lattices of its sulfide components, formation of So and 1/2Fe2O3·H2O, and change of chemical composition of pyrrhotite.

  2. 2.

    Preliminary mechanical concentrate activation quickens pyrrhotite degradation by 1.5–2 times and increases nickel and copper extraction by 1.8–2.8 and 1.5–2.0 times, respectively, this being supported by chemical and x-ray diffraction analyses. The experimental results for pulps of different densities are in agreement in this case.
