This work studies the leaching of copper contained in waste printed circuit boards (PCB) with ferric sulfate, with the aim of improving the results found in the literature for an industrial application of the process. For this purpose, temperatures and concentrations of ferric ion higher than those of previous works (up to 60 °C and 40 g/L) are...

PCBs constitute a residue rich in metals, among which copper stands out due to its majority content, much higher than that found in natural deposits, so that it is a potential secondary resource. Many attempts have been made to recover copper via biohydrometallurgy because it is an environmentally friendly route, however, one of its main...

Here, experimental data for the different stages of a bioprocess for obtaining copper from printed circuit boards are compiled. Chemical analysis data to determine the chemical composition of samples and residues. Conditions and results of batch and continuous leaching, solvent extraction, biooxidation and electrowinning tests are included.
