The bioleaching of flotation concentrate is a new method for copper recovery that could form the basis of an economic and environmentally friendly process. The main objective of this work was to evaluate a bioleaching process from the treatment of two concentrates, (i) a copper gold bearing concentrate and (ii) an ordinary copper flotation concentrate, using mesophilic bacteria. The special gold-bearing...
This study provides quantitative evidence for the adsorption of metal ions (Pb 2+ , Cu 2+ and Cd 2+ ) on the biomass of Nocardiasp. The adsorption of metal ions to the biomass varies with the type of metal cations and their electro negativity. It suggests that the adsorption of Pb 2+ , Cu 2+ and Cd 2+ is mainly due to electrostatic...
