    Copper activation option for a pentlanditepyrrhotite

    Introduction. Different sulphide ores respond differently in the prospect of copper activation to thiols for froth flotation. With the BCL Selebi Phikwe ore body, pentlanditepyrrhotitechalcopyrite co occur and there is the constraint of fine pentlandite dissemination in the pyrrhotite, so that liberation is limited.

    Copper Linked to the Onset of Alzheimer's Disease

    Any time you isolate one mineral and ingest it independently of the others, the potential exists for imbalance, or in the worst case, overdose, and this is true of zinc and copper. Just as zinc deficiency can lead to copper toxicity, taking too much zinc can interfere with your body's ability to absorb other minerals, especially copper.

  • Neutron activation

    Neutron activation

    Neutron activation is the only common way that a stable material can be induced into becoming intrinsically radioactive. All naturally occurring materials, including air, water, and soil, can be induced (activated) by neutron capture into some amount of radioactivity in varying degrees, as a result of production of neutron rich radioisotopes.
