    Sep 19, 2018 · In this research project in which we intend to design a process for recovery of precious metals from carbonaceous minerals which find the optimal conditions of the leaching process, then undertake the design and sizing of equipment required, taking into account the reagents ( thiosulfate and copper), and the parameters and process variables chosen.

  • Aplicación del proceso BRISA al tratamiento de menas de ...

    In order to improve the copper extraction yields, several treatment options are presented in this work, wich consist on promoting the acid leaching of the atacamite and the indirect bioleaching (BRISA process) of the secondary copper sulphides. All the options lead to improved copper recoveries in comparison with the current treatment.

    The flooded packed-bed bioreactor plays a major role in the field of applications of ferrous ion bio-oxidation. The pH is an important variable in the control of this type of reactor, upon which the functionality of biofilm depends.In the present work, five continuous flooded packed-bed reactors have been inoculated with mixed cultures (Acidithiobacillus ferrooxidans and Leptospirillum ...
