  • THERMOMECHANICAL ASPECT OF SELECTIVE FLOTATION OF ...

    finding selective collectors relative to pyrite and zinc in sepa-ration of copper and zinc minerals from pyrite [2]. However, with selective reagents in copper flotation, amount of sphaler-ite and fine-ground pyrite grows in the zinc flotation cycle, which mutilates flotation process. It is known that zinc cycle of

  • Selective Attachment of Leptospirillum ferrooxidans for ...

    The impact of selective attachment, bacterial growth conditions, and extracellular polymeric substances (EPS) was investigated through bio-flotation. L.f exhibits selective attachment to pyrite between 0 h and 168 h exposure via an indirect contact mechanism. Separation of chalcopyrite from pyrite was achieved through exposing the minerals for

  • Pyrite Depressant - Metallurgist & Mineral Processing Engineer

    In the work I conduct I have seen that altering the pulp chemistry can play huge roll in better selectivity against Pyrite. Typically changing media type from Forged steel to High chrome media can alter pulp chemistry to more oxidizing (or less reducing) conditions.
