  • Valorisation of a flotation tailing by bioleaching and ...

    10/1/2019· The bioleaching liquor, due to its content in ferric sulphate, can be directly used as leaching agent in the hydrometallurgical process for treating bulk Cu-Zn-Pb concentrate, giving savings in the process due to the high demand for Fe 3+. In addition, it contributes significant amounts of Cu and Zn put in solution during the bioleaching.

    Mineralization at La Mina is defined as a gold-rich polymetallic volcanic-hosted massive sulphide (VHMS) deposit which shows similarities to Noranda / La Ronde / Kuroko type Cu–Pb–Zn (±Au, Ag) massive sulphide deposits. Mineralization generally occurs as massive to semi-massive sulphide lenses within a calc-alkaline bimodal arc succession.
