  • Recovery of gold as by product from the base metals industries

    A lead gold pre float prior to the zinc flotation allowed the mine to recover 7,100 oz of gold in 1992, in a concentrate assaying 71 g/t Au. In general, however, the gold grade and the mineralogy do not allow the separation of gold from the zinc at the mine and gold is incorporated within the zinc concentrate, or is left behind with the pyrite, as is the case at the Olympias mine in Greece.
